Abstract

In this paper we consider an inverse problem of determination of a dielectric permittivity function from a backscattered electromagnetic wave. The inverse problem is formulated as an optimal control problem for a certain partial differential equation derived from Maxwell’s system. We study a solution method based on finite element approximation and provide a posteriori error estimate for the use in an adaptive algorithm.

Throughout the remaining part of the text we will use ‘≲’ to indicate approximate estimation in the following sense: \(a\lesssim b\) if and only if there exists a constant \(C>0\) and some \(b^*\approx b\) such that \(a\leq Cb^*\).
