Abstract

In this work, we propose a strategy for the construction of current sources that can control the electromagnetic (EM) fields in some near and far control regions embedded in multilayered media. By formulating the field with the current source using the integral equation and layered media Green's function (LMGF), the forward operator is defined. The Galerkin method is then applied to get the linear algebraic equations for such an inverse source problem, resulting in a discrete inverse problem. A regularization algorithm, such as truncated singular value decomposition (TSVD) is used to construct a stable approximate current source solution. Several relevant numerical examples are given to demonstrate the feasibility of the developed algorithms for the active control of the fields in layered media.
