Abstract :
A pyramidal radiowave absorber is widely used for anechoic chamber. When high power equipment such as radar is measured in anechoic chamber, a risk that the absorber will catch fire occurs by absorbing the high power. In this paper, effects of incident angle on both electromagnetic absorption and temperature characteristics of a pyramidal radiowave absorber are investigated by using the FDTD method and the heat-transfer analysis for both TE and TM waves.
