Abstract

The monostatic theorem of Weston states that a null RCS is observed for matched ε = μ objects with rotational symmetry. In this work we study a generalization of this result applied to heterogeneous magnetodielectric scatterers. The whole object of interest or the coating surrounding it is divided into a set of small cubical unit cells that are alternatively either purely dielectric or purely magnetic, i.e., the two materials are distributed in a lego format. Numerical computations are presented to compare the RCS levels of the original perfectly and the lego-based roughly impedance-matched scatterers.
