Abstract:
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 an agricultural material. The main material used in constructing the flat absorber is natural bamboo. The flat shaped absorber is selected as it able to meet the specified industry standard and can be used appropriately in the microwave frequency range. Carbon coated cylindrical bamboos with different radiuses have been used for this study. Studies were conducted on two different sizes of the radius that is 0.2 cm for Design 1 and 1 cm for Design 2. The ranges of frequencies are set in the range from 1 GHz to 12 GHz. The result of the microwave absorber is analyzed for its absorption performance. The generated result from the performance shows that the carbon-coated flat stick bamboo microwave absorber operates the best in Design 2 with 45.7% of absorption performance compared with Design 1. The overall results in different angles for both designs are analyzed and compared.
