Iterative time reversal retrofocusing of electromagnetic wave fields

Gustafsson, Mats LU and Jonsson, L (2004) International Symposium on Electromagnetic Theory (URSI EMTS 2004) In Proceedings International Symposium on Electromagnetic Theory p.224-226
Abstract
Time reversal is based on recording the wave field by a set of transducers, time reversing the recorded signal, and retransmitting the result. An iterative time reversal algorithm that retrofocuses an electromagnetic wave field to its controllable part is establish. The algorithm utilizes the 'equal fields on the boundary' condition, which can be archived with the wave-guided controllable part of the boundary. Numerical examples for the cavity and the half-space are given
