1/ Description Custom designs for a low-grazing application has lead to the development and manufacture of AEMI’s Millimeter Wave tapered absorbers. These materials were developed for chamber applications where main beam energy of the source antenna was focused on the sidewalls of the chamber, due to its long overall length. These materials were effectively used in the overall chamber design to provide the required test environment at 45 GHz.
