Abstract
The absorber used in anechoic and semi-anechoic chambers employed for emissions and immunity testing of digital devices is examined, Using r eflectivities obtained by the method of homogenization, the advantages and disadvantages of urethane pyramids, twisted-pyramids, wedges, as well as ferrite tiles, ferrite grids, and ''hybrid'' combinations of u rethanes and ferrites, are determined. General reflectivity guidelines are also presented for comparing absorber used for the electromagneti c compatibility (EMC) testing of digital devices from 30 to 1000 MHz.
