Abstract

The indirect modelling of electromagnetic scattering from two‐dimensional composite uniaxial bianisotropic cylinders of arbitrary cross‐section is successfully performed according to the principle of equivolumetric model. The mathematical treatment here is based on the generalized boundary‐value method combined with the technique of separate variables. The solution is obtained from a system of linear equations of infinite order which is then truncated during numerical computations. Then, numerical investigation is carried out to demonstrate hybrid effects of geometrical and constitutive parameters of guest and host cylinders on the co‐ and cross‐polarized echo widths in the far‐field zone. It is shown that under certain circumstances, the indirect modelling technique is very efficient to study the scattering characteristics of many practical complex planar structures, and has some advantages over the direct numerical method.
