Constructive adjustment of characteristic parameters of a mode-stirred reverberation chamber for EMC tests and power spectroscopy

The purpose of this work is to develop a knowledge base which allows for the assessment of the influence of individual construction parameters on a mode stirred chambers performance in its particular area of application. With this knowledge, it would be possible to adapt a chamber for a particular purpose, e.g. to use the chamber for electromagnetic compatibility test procedures or for power spectroscopic measurements. The scattering parameters as well as the field strength and the distribution of the electric field are employed to quantify the influencing construction parameters of the chamber. In addition, a concept for a 3D positioning system is presented which can be used to accurately measure the electric field in the chamber. This is necessary in order to be able to make statistical statements about the electric field distribution.
