    • "The pyramidal microwave absorber design is based on these papers and journals [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] [40]. In this work, the mixtures of this absorber are banana leaves, polyester as resin and methyl ethyl ketone peroxide (MEKP) as hardener agent. "

    ABSTRACT: Abandoned agricultural waste pose a risk to the environmental and public health. The polyurethane and polystyrene material for designing pyramidal microwave absorber are expensive and not environmental friendly. Tropical crop residue has potential to be used in the electromagnetic testing area. Nowadays, electromagnetic absorbing materials have been increasingly important in ensuring successful Radio Frequency (RF) anechoic chamber testing performance. New material had been research to reduce the cost of designing pyramidal microwave absorber. In this case, dried banana leaves are mixed with polyester and methyl ethyl ketone peroxide (MEKP) to give the best reflection loss performance to the pyramidal microwave absorber compare to the previous research using rice husk. This pyramidal microwave absorber is operating in the frequency range from 0.1 GHz to 20.0 GHz.

    ABSTRACT: Waste material has potential to be used as an alternative material for the microwave absorber that used in the RF anechoic chamber. New material had been research to reduce the cost of designing pyramidal microwave absorber. In this research, rice husk from paddy are mixed with recycled rubber tire dust to give the better reflection loss performance to the pyramidal microwave absorber design. The pyramidal microwave absorber is operating in the microwave frequency range from 7 GHz to 12 GHz. There are three main stage of this work. Firstly, fabricate the waste material pyramidal microwave absorber had been done by using the pyramidal shaped mould. The second work is to determine the dielectric properties of the pyramidal microwave absorber and the last stage is to measure the reflection loss of the waste material using the radar cross section (RCS) technique.

    ABSTRACT: Sugar cane bagasse as is potential agricultural waste to produce an alternative and beneficial product for any suitable application such as pyramidal microwave absorber for anechoic chamber testing application. In this work, the dielectric properties (dielectric constant and tangent loss) of the sugar cane baggase had been measured using the dielectric probe measurement. The sugar can bagasse pyramidal microwave absorber had been modelled and simulate in the CST Microwave Studio using the data from the dielectric probe measurement.
