Electromagnetic Time Reversal for Radiating Source Identification in Time Domain

Résumé

This paper presents a study on the characterization of electromagnetic near field radiation in the time domain. The proposed methodology affords a radiation model based on the electromagnetic inverse method using analytical expressions of the equivalent dipoles. The identification procedure is conducted by the Time Reversal technique (TR). The advantage of this process is focusing a field in both time and space. The main goal of this paper is to investigate the use of the Electromagnetic Time Reversal (EMTR) method in the time domain. First, the EMTR principle is presented. The characterization of the time domain magnetic field distribution is then developed. The radiating source localization and the excitation signal's shape were successfully defined. In addition, the calculated distribution cartography of the magnetic field is compared to the reconstructed cartography. The obtained results show the effectiveness of the proposed approach.
