A load effect evaluation of a transmission line exciting chamber

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.
