Numerical Evaluation of Noncanonical Reverberation Chamber Configurations

This paper aims to present an evaluation of noncanonical mode stirred chambers, whose excitation is carried out by transmission lines. Many configurations are taken into account regarding the influence of the wire arrangement and their phase shift excitation on the field homogeneity. The simulations were carried out within the framework of finite integration technique (FIT) and transmission-line modeling (TLM) methods. Experimental and theoretical results are presented regarding the chamber suitability to electromagnetic compatibility (EMC) tests. It is emphasized the viability of extending the present standard frequency range recommendation to lower frequency values.
