Abstract

Pyramidal radiowave absorbers are widely used for anechoic chambers. Therefore, it is important to know the electromagnetic absorption and temperature distribution characteristics of the absorber. Traditionally, a pyramidal radiowave absorber has been designed by using an approximate design method. Therefore, it seems important to design a pyramidal radiowave absorber accurately by using a numerical simulation. In this paper, effects of the height and width of pyramidal radiowave absorber on both electromagnetic absorption and temperature distribution characteristics are investigated through the electromagnetic and heat-transfer analyses using the FDTD method.
