Reconstruction of nonlinear material properties for homogeneous, isotropic slabs using electromagnetic waves
Author
Summary, in English
This paper addresses the inverse problem of reconstructing a medium’s instantaneous,
nonlinear response to electromagnetic excitation. Using reflection
and transmission data for an almost arbitrary incident field on a homogeneous
slab, we are able to obtain the nonlinear constitutive relations for
both electric and magnetic fields, with virtually no assumptions made on the
specific form of the relations. It is shown that for a nonmagnetic material,
reflection data suffices to obtain the electrical nonlinear response. We also
show that the algorithms are well posed. Numerical examples illustrate the
analysis presented in this paper.
