Directive Wavefronts Inside a Time Reversal Electromagnetic Chamber


In this paper, the feasibility of directive wavefronts generation inside a time-reversal electromagnetic chamber (TREC) is investigated in order to propose the TREC system as an alternative EMC test facility. This may be accomplished by applying the time reversal technique on electromagnetic waves inside a reverberation chamber. We evaluate the performance of the TREC in creating directive radiation patterns towards an equipment-under-test (EUT). This evaluation is based on the directivity comparison of a wavefront generated by the TREC, and the one generated by a theoretical model of an antenna array in free space. Numerical simulations of the TREC are in a good agreement with the theoretical array model, showing a root-mean-square (rms) deviation from the mean value of the E-field, over a 3 dB main lobe angle, below 6 %.
