Influence of the Properties of a Real Semi Anechoic Chamber on an Internal Electromagnetic Field Distribution
Authors: , ,
Abstract: This paper describes an experiment dealing with monitoring of an electrical field displacement within a real semi anechoic chamber of an irregular shape. The experiment is based on the assumption that the semi anechoic chamber acts as a cavity resonator, and the possibilities of the internal frequency modes of damping are technically limited. In semi anechoic chambers for electromagnetic compatibility testing, this phenomenon leads to a variation of the field strength in the space of the chamber, which may affect the accuracy of the measurement. Therefore, accurate mapping of the chamber’s influence to the measurement can help the engineers to improve the methods of equipment testing on electromagnetic compatibility, making it faster, more accurate and more controlled. An example of a response of the semi anechoic chamber operated at Tomas Bata University in Zlin is provided within the framework of this paper, as well as a discussion on the results obtained.
