The layer-stripping algorithm for reconstruction of dielectrics in an optical fiber

Paper in proceeding, 2015

We present a new model of an approximate globally convergent method in a frequency domain for reconstruction of dielectric permittivity of a weakly guiding optical fiber. We consider data which are given only at the backscattered side of the medium which should be reconstructed. We formulate new approximately globally convergent algorithm for the reconstruction of dielectric permittivity function under the assumption that the magnetic permeability is a known constant.
