p>The widespread of coronavirus disease 2019 (COVID-19) pandemic led to a discovery that open distance learning (ODL) has turned out to be the only choice for teaching and learning by most institution (s) of higher learning (IHLs). In Malaysia, ODL is considered a new approach as physical laboratory practice has always been conducted for laboratory...

span>Electromagnetic interference (EMI) is an undesired electromagnetic (EM) wave by nearby electronic devices, process equipment, and measuring instruments. In this work, a novel multi-slot technique is applied to the hollow biomass pyramidal microwave absorber to study its absorption properties thoroughly. Two different slot arrangements in horiz...

Electromagnetic elimination was used to eliminate unwanted radiation that may interface with machinery or affect human health. The use of microwave absorbers has become necessary for an environment with a safe electromagnetic wave level. The objectives of this project are to design a microwave absorber as a modern biomass wall tile and to investiga...
Article
Electromagnetic radiation can be prevented by using microwave absorber. Microwave absorbers are applied in an anechoic chamber for the electromagnetic compatibility (EMC) and electromagnetic interference (EMI) evaluation on its wall, ceiling, and floor. The purpose of this research is to develop a carbon-coated flat shape of biomass absorbers using...
Chapter
This paper investigates the performance of multilayer pyramidal hollow green biomass coated absorbing materials. The designed absorber is simulated using CST Microwave Studio. Several experimental evaluations have been executed to investigate the performance of the tested absorber using free space arch measurement method. The frequency between 8 an...
Article
This paper will introduce the new technique to design new type of microwave absorber. Microwave absorbers are used in anechoic chamber to diminish the unwanted RF signal, so that the measurement obtain have perfect and good results. The basic theories of slot antenna combining with the theory of microwave absorber are used in this paper. As a resul...
Conference Paper
This paper presents the performance effect of hollow pyramidal microwave absorber that had been applied with slotted array principle. The Sierpinski triangle was used as the slotted on the hollow pyramidal microwave absorber. This paper includes the theories, simulation and measurement result. The simulation using CST Microwave Studio Suite used to...

This paper investigates the effect of PVDF-TrFE layer to the electrical properties of MIS device. The MIS (Al/PMMA:TiO2/PVDF-TrFE/Si) structures were fabricated on n-type Si substrate. The results indicate that the properties of MIS improved drastically with PVDF-TrFE layer. I-V and C-V characteristics shows that the MIS has a fast operating voltag...
Conference Paper
MOS device is mostly used due to the properties of low-voltage, high-speed, and high-integration. In this work, electrical characteristics of MOS capacitor with various sizes of areas are analyzed at quasi-static frequency. The measurement of capacitance versus area of capacitor (C-A) for representative MOS capacitors are obtained. The C-A measurem...
