  • Trends and prospects in solution-cast polymer electrolytes: From processing simplicity to performance complexity
    Abdullahi Abbas Adam, Norazwina Zainol, Theodore Azemtsop Manfo, Mohamad Shaiful Abdul Karim
    Journal of Energy Storage, 2026
    Solution casting, once valued for its simplicity as a film-forming technique, has now matured into a versatile and powerful route for designing advanced solid and gel polymer electrolytes. Its low cost, reproducibility, and adaptability uniquely position it to bridge fundamental materials science with practical device integration. In recent years, solution-cast polymer electrolytes have evolved beyond processing simplicity to becoming engineered platforms where ion transport pathways, structural architectures, and additive chemistries are tailored. This evolution addresses intrinsic limitations such as low room-temperature conductivity, poor interfacial contact, and fragile mechanical strength. Advances stem from approaches that control polymer crystallinity, strengthen polymer-ion interactions, and use of electrolyte additives (such as plasticizers, fillers, MXenes, metal organic frameworks and deep eutectic solvents) to elevate ionic conductivity, widen electrochemical stability windows and promote mechanical robustness. At the same time, the incorporation of bio-based and recyclable polymers has extended these advances into the realm of sustainability, aligning electrolyte innovation with environmental responsibility. Together, these developments demonstrate how a simple processing method has given rise to performance complexity, enabling polymer electrolytes to compete with their liquid and inorganic counterparts. This review critically evaluates these advances, tracing how processing innovations translate into functional performance. It also highlights the trends and prospects most likely to shape the development of frontier solid-state batteries and supercapacitors.

    Journal of King Saud University Engineering Sciences, 2026
    The development of sustainable dielectric materials is crucial for advancing next-generation electronic and energy storage systems. This study investigates the dielectric behavior of coconut-shell-based epoxy composites and evaluates the influence of processing parameters using a two-level factorial design (TLFD) coupled with two-level factorial analysis (TLFA). The effects of filler loading, particle size, and curing condition (non-heated and heated) on lignocellulosic content and the real part of permittivity (ε′) were systematically examined at 5 GHz using a vector network analyzer. At a 40 wt.% filler content, the measured lignocellulosic content reached 58.7% (Kurschner-Hanack), with permittivity values ranging from 3.74 to 4.11. Statistical analysis identified the curing condition as the most significant factor affecting ε′, followed by filler loading and particle size. The novelty of this study lies in applying TLFD and TLFA to quantitatively evaluate how lignocellulosic content influences GHz-range permittivity specifically in coconut-shell-based dielectric composites, a compositional factor that earlier coconut-shell studies have not explicitly examined. This approach demonstrates how statistical modeling, supported by ANOVA, can bridge the relationship between material composition and electromagnetic performance in GHz dielectric composites. The findings establish a systematic framework for optimizing bio-based dielectric materials and demonstrate the potential of coconut-shell-derived composites for sustainable electronic applications.
  • Active antennas in focus: A systematic review of technologies, performance, and limitations in comparison to passive antennas
    Imadeldin Elmutasim, Mohamad Shaiful, Izzeldin Ibrahim
    Proceedings of SPIE the International Society for Optical Engineering, 2026
    Integrating active devices in antenna systems highly improves its functionality over the traditional antenna systems that are passive in nature and therefore this aspect is of great focus to modern communication technologies. A systematic review compared both passive and active antenna strategies, noting that the possible gain benefits of active systems could be achieved. An analysis was conducted on both active and passive antennas at frequencies of 1, 3, 5, 7, and 10 GHz to elucidate the impact of active components on antenna efficacy, while a ±0.5 dB uncertainty margin was introduced to reflect typical amplifier tolerance. The results showed a figure of 6 dB gain at 10 GHz compared to the 2 dB reported by the passive antenna at the same frequency. Further analysis at 2.4 GHz indicated that the active antenna showed an increase in the radiation of 20 dBi over its passive alternative, and thus the effective use of active antennas was confirmed, leading to major applications of wireless communication.
  • Rectifier antenna for wireless solar power transmission: Efficiency analysis across multiple frequency bands
    Imadeldin Elmutasim, Mohamad Shaiful, Izzeldin Ibrahim, Khalid Hamid, Mohamed Hassan
    Proceedings of SPIE the International Society for Optical Engineering, 2026
    Rectifier antennas play an important role in wireless energy transfer and space-based solar power (SBSP) systems, as they directly convert incident microwave energy into useable DC power. This paper is a comparative simulation study of rectennas under four frequency bands: 0.9 GHz, 2.45 GHz, 5.8 GHz, and 10 GHz. Analysis of rectification efficiency and DC output power as functions of the RF power is performed using MATLAB-based modeling. The findings indicate that rectenna efficiency can be sensitive to frequency, with the 2.45 GHz band realizing overall maximum performance (a 70 percent efficiency). A system-level comparison between rectennas and terrestrial photovoltaic (PV) systems underscores the advantage of rectennas in providing continuous, stable power, overcoming PV’s intermittency due to weather and nighttime unavailability. The results show that the rectennas at similar 2.45 GHz ISM band offer a viable solution to high-conversion-efficiency, large-scale wireless power transport.
  • A Comprehensive Review of Maritime Wireless Propagation: Salinity, Humidity, and Evaporation Duct Effects on 5G/6G Networks
    Imadeldin Elsayed Elmutasim, Izzeldin Ibrahim Mohamed, Alia Al-Shidi, Khalid Hamid Bilal, Mohamed Hassan, Nur Sofia Idayu Didik Aprianto, Mohamad Shaiful Abdul Karim
    IEEE Access, 2026
    Maritime and coastal communication systems are becoming increasingly critical for shipping, offshore industries, naval operations, and emerging applications such as the maritime Internet of Things (IoT), autonomous vessels, and coastal 6G networks. Unlike terrestrial environments, radio wave propagation over sea channels is strongly influenced by unique environmental factors, including salinity-dependent dielectric properties of seawater, high relative humidity, evaporation ducts, and sea surface roughness. These conditions alter reflection, scattering, and absorption mechanisms, leading to significant deviations from conventional terrestrial propagation models. Traditional methods such as the Free-Space Path Loss (FSPL), Two-Ray Ground Reflection (2-RGR) model, and ITU-R recommendations provide useful baselines but fail to fully capture the combined effects of salinity, humidity, and refractivity structures. This review consolidates state-of-the-art research on maritime wireless propagation by classifying existing models into theoretical, empirical, measurement-based, and machine learning-driven approaches, highlighting their strengths, limitations, and validation scenarios. Special attention is given to the role of evaporation ducts in extending communication ranges, the impact of salinity on seawater dielectric constants, and humidity-induced attenuation at high-frequency bands. The review also identifies open research challenges such as the scarcity of large-scale maritime datasets, limited validation at millimeter-wave and terahertz frequencies, and the need for hybrid AI-physics models. The insights presented here aim to support the development of more robust propagation models and adaptive techniques for future 5G/6G maritime networks.

    Azahani Natasha Azman, Rudraa Devi Giamasrow, Nurfarhana Mustafa, Nurhafizah Abu Talip Yusof, Norazwina Zainol, Izzeldin Ibrahim Mohamed Abdelaziz, Ayib Rosdi Zainun, Mohamad Shaiful Abdul Karim
    Journal of Advanced Research in Applied Sciences and Engineering Technology, 2025
    Pineapples generate approximately 75% waste, each with its unique characteristics. Pineapple leaves have the potential to be utilized in the development of new fibres or raw materials. This study aims to present the design of a microstrip patch antenna that utilizes a pineapple leaf substrate to achieve a 5 GHz frequency resonant. The antenna design was simulated using CST software. The manufacturing process of the pineapple leaf substrate involves boiling, drying, blending, filtering, and mixing composite compositions. The dielectric permittivity at a frequency of G-band was determined using the waveguide technique, revealing an outstanding permittivity of 5.03 at 5 GHz. Subsequently, a microstrip patch antenna was fabricated and characterized to validate the concept. The results demonstrate an acceptable agreement between the simulation and the fabricated substrate at 5 GHz in term of return loss.
  • Surface analysis of pineapple leaves pulp-based dielectric composite material and its dielectric performance
    M.S. Abdul Karim, N. Zainol, N.H. Aziz, M.J.M. Fikry, N.A.T. Yusof
    Next Materials, 2025
    The integration of cellulose fiber composites into material engineering marks a pivotal step toward sustainable development. In this study, dielectric composite materials derived from pineapple leaf pulp were analyzed for their surface characteristics and corresponding dielectric performance. Cellulose fibers were extracted from pineapple leaves using a soda pulping method, with cellulose content quantified through the Kurschner-Hanack technique. The developed composite, comprising cellulose fibers, epoxy resin, and hardener, was evaluated for its permittivity using a waveguide technique in the G-band. Surface morphology was assessed through scanning electron microscopy (SEM), while elemental composition was determined via energy-dispersive X-ray (EDX) spectroscopy. Results indicated a cellulose content of 59 % and a permittivity value of 3.27. The surface analysis revealed that fiber diameter plays a critical role in influencing both cellulose content and permittivity, with increases in fiber diameter leading to higher values for both. Elemental analysis identified carbon, oxygen, sodium, calcium, silicon, aluminum, and potassium in the fibers, with carbon being the most prevalent. This study highlights the direct influence of fiber morphology and elemental composition on the dielectric performance of pineapple leaf-based composites, offering a sustainable pathway for advanced electronic materials development. The observed dielectric properties suggest that this cellulose fiber composite could potentially serve as a sustainable alternative to conventional capacitors in electronic applications.
  • Potential of wastewater quality assessment using electronic sensors: A review
    Karim M.S. Abdul, N.A.T. Yusof, N. Zainol, N.H. Aziz
    Research Journal of Chemistry and Environment, 2025
    Untreated wastewater and improper wastewater treatment from domestic and industrial sources continue to degrade water quality around the globe. The greatest challenge currently lies in shifting our perspective on wastewater, aiming to perceive it not merely as a problem but as a potential solution. Several challenges have limited wastewater monitoring and assessment. These limitations include real-time monitoring and aging infrastructure, which can impact the accuracy, efficiency and reliability of the obtained information. These conventional assessment methods are unable to handle the increasing volume and complexity of contaminants in modern wastewater, resulting in poorly treated wastewater. To address this issue, an electronic sensor has been introduced to overcome such crises, providing a better assessment of wastewater quality. Electronic sensors offer a real-time and efficient means to evaluate various parameters in wastewater, providing valuable insights into the composition and potential environmental impact. The potential of wastewater quality assessment using electronic sensors represents a promising avenue in modern environmental monitoring. This innovative approach allows for continuous and automated monitoring, enabling timely detection of changes in water quality. The utilization of electronic sensors in wastewater assessment holds the potential to enhance our understanding of pollution sources, to facilitate rapid responses to environmental challenges and to contribute to the sustainable management of water resources. In this review, a comprehensive study was performed on electronic sensors to evaluate their physical and chemical properties, as well as a microbial analysis for wastewater quality assessment. Possible challenges and future directions for their development have also been investigated critically. This study will assist future research on electronic sensors which will be highly important for sustainable wastewater assessment.

    Md Mahabub Alam, Nurhafizah Abu Talip Yusof, Nurazyyati Inas, Muhammad Naim Aminuddin, Bifta Sama Bari, Yasmin Abdul Wahab, Mohamad Shaiful Abdul Karim
    Diyala Journal of Engineering Sciences, 2025
    This paper presents the design and performance evaluation of a Substrate-Integrated Waveguide (SIW) antenna fabricated using 3D printing technology, with a focus on optimizing its performance for future free-space applications. The proposed antenna integrates an SIW structure with a horn antenna concept, effectively combining the transmitter and receiver functions into a compact, monolithic substrate. This approach provides a miniaturized alternative to conventional free-space material characterization setups, leveraging SIW technology to replace bulky horn antennas with integrated structures. The study demonstrates the feasibility of compact free-space techniques for non-destructive testing, sensing, and electromagnetic material characterization applications. The study involves modeling and simulation using Computer Simulation Technology (CST) software, focusing on antenna performance in the G-band range (4–6 GHz). The fabricated prototype demonstrates resonant frequencies at 5.02 GHz and 6.0 GHz, with a scattering parameter below -10 dB and a well-defined radiation pattern, exhibiting sidelobes at -2.7 dB. The antenna is fabricated using biodegradable Polylactic Acid (PLA) material, reinforcing the potential for sustainable electronics while maintaining structural integrity and electromagnetic compatibility. While this study does not yet validate the antenna for material characterization, the results confirm its feasibility as a compact, cost-effective alternative to conventional free-space setups. This work lays the foundation for further optimization and experimental validation, advancing the role of 3D-printed SIW antennas in free-space applications.
