A Circuital Approach to Control the Response of Conformal Metasurfaces

In this paper we introduce an analytical method to control the response of conformal metasurfaces with respect to an impinging plane wave as excitation source. We first develop and present the analytical framework in order to achieve a full control over the current distribution within the metasurface. Then, in order to prove the theoretical model, we design a test-case through a numerical solver, consisting in a curved magnetic metasurface excited by a plane wave. The obtained numerical results are in excellent agreement with the theory, confirming the validity of the proposed approach. In this way, an accurate and effective control over conformal magnetic metasurfaces can be accomplished, extending the possible technological applications with respect to the traditional planar configuration.
