Abstract
Quantifying the degree of non linearity with respect to the permittivity profile represents in interesting possibility for quantifying the difficulty of both forward and inverse scattering problems. With reference to the 2D case, in this paper new tools are proposed that allow to determine the degree of non linearity while changing maximum value, dimensions and spatial frequency content of the unknown permittivity profile, as well as polarization of the incident field. As such, the proposed tools allow to identify new solution strategy for the inverse problem and the simpler nature of the TE (vectorial) problem. Numerical examples support the conclusion.
