Abstract
Semianechoic chambers are the most widely used emplacements
for Electromagnetic Compatibility (EMC) Tests. Semianechoic
chambers design is not an easy task, since they must behave like
an ideal Open Area Test Site (OATS) within a quite narrow
margin (±4 dB) in a wide frequency span (from 30 to 1000 MHz).
There are several possible configurations for a Semianechoic
Chamber, based on different technological solutions (dielectric
foam absorbers of different shapes, ferrite absorbing tiles or a
combination of both elements are found in most of the actual
chambers). In this work a new and efficient technique for the
analysis of 2-D simplified model of a chamber with arbitrary
absorber is introduced and validated. Some advanced results are
presented, and a 2-D estimator for studying the overall behaviour
of the chamber is proposed.
