Abstract The performance of absorbers in anechoic chambers (ACs) is optimized in a
full wave analysis method, with regard to carbon loading, blunt tip, hollow type and
other geometric structure of absorbers. The effect of different sizes of ACs on the
performance of absorbers, as well as hybrid absorbers is studied herein. The criteria of
absorbers fitting for ACs are provided, too. The analysis can be a guide for the
manufacturing and choosing of absorbers.
