Multilayer performance of green biomass coated pyramidal hollow microwave absorber

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 and 12 GHz was selected for performance evaluation. The results show that, the multilayer pyramidal shaped of microwave absorber produces excellent performance results.
