Abstract :
An iterative technique for improving the temporal focusing of a time reversal mirror is proposed and tested. A single amplification parameter is introduced to tune the convergence of the iteration. The tunable iterative technique has been validated by tests on an experimental electromagnetic time reversal mirror, as well as on a novel numerical model.
