kansas enrollment Abstract: This tutorial includes a brief introduction to anechoic chambers and absorber technology. It shows a typical, basic approach to anechoic chamber design for different applications from electromagnetic compatibility (EMC) and radar cross section (RCS) measurements to antenna pattern measurements (APM). Published in: CPEM 2010.Anechoic chambers are made by lining the walls, floor, and ceiling with fiberglass wedges that absorb sound. The wedges are arranged in a network so that sound waves are reflections are dissipated. For radio anechoic chambers, the wedges are made of radiation-absorbent material.
