Resumo Inglês:

This paper presents an evaluation of the phase shifting
excitation and load effects in a Transmission Line Exciting
Chamber. 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.
