Agriculture waste has huge potential to be used as an alternative material for constructing microwave absorber which is typically used in an anechoic chamber. The existing microwave absorbers are normally manufactured from chemical substances. This project is proposing the use of a new composite biomass material namely coconut coir, for constructin...
Article
Radiation Absorbing Material (RAM) is used to absorb radiations of electromagnetic wave surrounding us. Thus, the multiple layers’ microwave absorber using biomass composite materials could be one of the solutions to address the problem. In order to effectively absorb the radiation of electromagnetic wave, the multiple layers’ absorber is character...
Conference Paper
An anechoic chamber is considered good when there is no signal reflection inside the chamber and also when there is no incoming signal from outside the chamber. The key element inside an anechoic chamber is the absorbing material. The evaluations of mini anechoic chamber fitted with coated absorbers were carried out by analyzing the absorption perf...

T-way strategy has been known to be effective in generating test data and addressed combinatorial explosion issue. This paper describes the design and development of a non-deterministic t-way strategy, called TTG, with seeding and constraints support. In doing so, a number of experiments are discussed in order to prove the correctness of the implem...
Article
The most important part to be highlighted in developing a reliable microwave absorber is the material used to fabricate the absorber. As an alternative in managing the increase of the oil palm residues throughout the country, this study is focusing on developing a microwave absorber coating using oil palm fly ash. The software uses for design and s...
Conference Paper
The investigation of oil palm ash microwave absorbers involves the design, simulation and fabrication of an effective broadband frequency for anechoic chamber. The resistive and magnetic materials in the oil palm ash compose its potential to be used as microwave absorbing materials. These oil palm ash absorbers are simulated using CST Microwave Stu...
Article
Microwave absorbing materials have received great attention in recent years for both civil and military fields due to various applications in communications, radar, satellite systems, and anechoic chambers.Wireless communication is currently the fastest growth of telecommunication technology.Many studies have indicated that there are harmful radiat...

... The form of a pyramidal absorber could be solid or hollow in design. Most of the investigations reported earlier involved solid forms but recently, studies on hollow is being carried out since the structures will be beneficial in reducing the overall weight of the absorbing material used within an anechoic chamber facility [23], [24]. The slot array, which comprises of capacitive cells, acts as a capacitor in the low frequency domain but, after the first resonance, its impedance becomes inductive [25]. ...
... such as pyramids, truncated pyramidal, bobbin systems, hybrid absorbers, absorber types of metamaterials and others, are available as absorbers [2]- [6]. ...
... The measurement setup comprises two horn antennas installed facing each other, absorbers to be measured and measurement software (Agilent 85071E) [10]. The two antennas are positioned in a constant distance from the testing material on a reflective metal plate below. ...
... In the last decade, combinatorial interaction testing strategies were focused on 2-way (pairwise) testing. More recently, several strategies have been developed on in the past (e.g., IPOG [3], MIPOG [4], GMIPOG [5] and TTG [6]) that can generate test suite for high degree interaction (2 previous work associated with cumulative interaction in order to facilitate the characteristics of cumulative T-way strategy. ...
... Biowaste such as bagasse is a very efficient material for microwave absorption and is reported better than rice husks due to its more carbon content. Noordin et al. (2012) reported the fabrication of microwave absorber using oil palm ash. The chemical composition of oil palm ash consists of CaO, MgO, SO 3 , K 2 O, SiO 2 , Fe 2 O 3 and CO 2 . ...
