Modeling the Electromagnetic Field Distribution Inside an Anechoic Chamber Lined with Different Types of Radio-Frequency Absorbers

This paper presents some aspects regarding the electromagnetic field distribution modeling within an anechoic chamber lined with different radio-frequency absorbing materials, according to the Faraday cage principle. In order to model the distribution of the electromagnetic field inside the anechoic chamber, the CST Studio Suite simulation software was used. The modeling was performed for two types of absorbers: 3650-40- ML and 3650-50-CF. After analyzing the results obtained from the simulation of the electromagnetic field distribution, it was observed that for the frequency range 1 GHz -:- 4 GHz the performance of the 3650-40-ML material is better than that of the 3650-50-CF material. Above the frequency of 2 GHz, the performance of the two materials was similar.
