A new layer-peeling algorithm for lossy media without using phase information

Abstract

Layer peeling algorithms have been used for past forty years to solve a wide variety of one-dimensional lossless inverse scattering problems, ranging from the Earth sounding to the speech sound synthesis. In this paper we present yet another layer peeling algorithm that operates on the intensity signals (with no phase information) applied to lossy media. The proposed algorithm was verified experimentally using fiber optic directional couplers.
