Spatial field intensity shaping via optimized multi target time reversal

Generating a given field intensity distribution in a non homogeneous scenario is a problem of interest in many applications. Due to the challenging nature of the problem, very few approaches have been presented so far, and none of them has fully addressed all the pertaining issues yet. In this communication we present an innovative and relatively simple shaping approach that relies on an optimized version of the well know time reversal method, named Optimized multi target Time Reversal. To appraise the performances of the proposed approach, a numerical assessment and a comparison with a recent and related shaping procedure available in the literature is reported.
