Single-Sensor EMI Source Localization Using Time Reversal: An Experimental Validation

The localization of electromagnetic interference (EMI) sources is high importance in compatibility applications. Recently, a novel technique based on the time-reversal cavity (TRC) concept was proposed using only one sensor, and its application to localize EMI validated numerically. In this paper, we present validation process which forward step performed experimentally backward carried out via numerical simulations, realistic scenario applicable practical source problems. To best authors’ knowledge, first implementation three-dimensional signal provided while propagation considered experimental setup formed by partially open two monopole antennas emulate sensor (receiving antenna), respectively. Assuming that location feed point antenna, resulting error 1.49 cm, about one-third length corresponding ?min/2 (diffraction limit).
