Abstract

This paper analyses the reflection level of absorber used in anechoic chamber by FDTD. Reflection level can be got by calculating one element when considering the periodic boundary. Excitation source is introduced into the total field by using total-field/scattered-field technique, and asymmetric grid is adopted to solve incident wave with large-angle. At last all kinds of rule about reflection level are researched. This paper has great value in analyzing electromagnetism environment and design of absorber.
