Show affiliationsA frequency-domain inverse scattering problem for inhomogeneous media with spatially varying dispersion characteristics is considered. The standard classical dispersion law for an isotropic semi-conducting dielectric is presented in a generalized form with frequency and spatial dependencies separated. Subsequent discretization in the dispersion parameters space allows for an efficient multi-source, multi-frequency formulation of the problem. Numerical examples of two-dimensional linearized inversion in the neighbourhood of absorption lines and for media with relaxation are presented.
