Abstract
A phase conjugation algorithm for localizing an extended radiating electromagnetic source from boundary measurements of the electric field is presented. Measurements are taken over a finite number of frequencies. The artifacts related to the finite frequency data are tackled with regularization blended with the fast iterative shrinkage-thresholding algorithm with backtracking of Beck & Teboulle.
