Investigation of sugar cane bagasse as alternative material for pyramidal microwave absorber design

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. This pyramidal microwave absorber had been operating in the microwave frequency range between 0.1 GHz to 20.0 GHz. The targeting reflection loss of this pyramidal microwave absorber is better than - 30 dB. The reflection loss performance comparison with the rice husk also had been done in this work.
