Electromagnetic imaging in stratified media by means of a finite-element variable-exponent inversion approach

Description

An electromagnetic imaging technique for the characterization of targets embedded in stratified media is proposed. The method aims at reconstructing the distributions of the dielectric properties from scattering S-parameters measurements through a non-linear inversion technique in variable-exponent Lebesgue spaces merged with a finite-element formulation. The proposed method is validated in a numerically simulated three-layer scenario involving both single and multiple targets, showing good reconstruction capabilities.
