This paper presents an evaluation of the phase shifting excitation and load effects in a Transmission Line ExcitingChamber. This chamber is suggested as an alternative for immunity tests because of the restrictions related to canonical chambers. Here, two methods are used to calculate the E-field: a semi-analytic approach and a numerical one. The semi-analytic method is based on the modal expansion while a software is used for numerical simulations. The results regarding the E-field profile and the related statistical indexes of merit are presented and used to evaluate the chamber performances. Experiments were also conducted in order to evaluate the chamber.Index Terms-Reverberation chamber, random excitations and loads, transmission lines.

“…The optimization techniques are used to search the working volumes [5], [6] that fulfill predefined requirements of field uniformity and mean electric field. This paper takes into account a predefined chamber, i.e., both the dimensions of the chamber and the position of the wires are known and will be not changed.…”

This paper presents a procedure for evaluating the performance of reverberation chambers, by approximating the maximum working volume in a given configuration. The evaluation of this volume is based on the geometrical and physical constraints, e.g., the ones related to the internal E-field distribution recommended by standards. The importance of the present work is related to the development of a non-canonical reverberation chamber configuration, whose excitation is carried out by transmission lines, instead of antennas plus paddles.
