Show affiliationsNonlinearized electromagnetic inversion of a three-dimensional homogeneous model of arbitrary but known support is considered. We propose a reduced-order representation of the cost functional based on the shift invariance property of the Arnoldi decomposition. Numerical experiments demonstrate acceleration up to a factor of 100 with respect to the usual repetitive solution of the forward scattering problem. We also discuss the applicability of a homogeneous model for estimating the effective constitutive parameter of an inhomogeneous target.
