Electromagnetic Time Reversal robustness for EMC applications

The proposed work deals with the robustness of electromagnetic time reversal (ETR) process. Many studies were achieved covering a huge diversity of domains: communication (A. Tourin et al., Nato Sciences Series, II, 2003), imaging (D. Liu et al., IEEE Trans. on Ant. and Prop., 2005), focusing (M. Davy et al., Comptes Rendus Physiques, 11, 2010, pp. 37–43). In this framework, electromagnetic compatibility (EMC) may take large benefits from ETR (H. Moussa, PhD thesis, Univ. Paris 11, 2011) since it allows a potential control of electromagnetic (EM) waves. This could potentially decrease time and costs during EMC standard tests assuming external conditions (antennas location, environment, devices under test properties) are perfectly known (ideal case rarely encountered). Few studies (G. Papanicolaou, SIAM, 2004, pp. 1133–1155) were achieved to assess the potential impact of randomness on ETR. The purpose of this paper is to put the focus on the robustness and the diversity of using TR for EMC: shielding effectiveness, EM field controlling, wire diagnosis for instance.
