This paper is to study the performance of rice husk and rice husk ash (RH-RHA) mixture material as a microwave absorber. The microwave absorption and dielectric properties, ε of RH-RHA mixture with different ratio were investigated in microwave frequency region 8.2 to 12.4 GHz (X-band). A waveguide transmission line method (Nicholson-Ross-Weir) was used to measure the complex permittivity of RH-RHA with different weight ratio mixture. The RH-RHA microwave absorbers were designed and simulated in CST-MWS. The various ratio RH-RHA mixtures show the different dielectric properties and the microwave absorption was investigated. The 60%RH-40%RHA microwave absorber has the best microwave absorption 46–76%.
