Indirect modelling of the scattering from two-dimensional composite uniaxial bianisotropic cylinders of arbitrary cross-sections

The indirect modelling of electromagnetic scattering from two-dimensional c omposite uniaxial bianisotropic cylinders of arbitrary cross-section is suc cessfully performed according to the principle of equivolumetric model. The mathematical treatment here is based on the generalized boundary-value met hod combined with the technique of separate variables. The solution is obta ined from a system of linear equations of infinite order which is then trun cated during numerical computations. Then, numerical investigation is carri ed out to demonstrate hybrid effects of geometrical and constitutive parame ters 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 i ndirect modelling technique is very efficient to study the scattering chara cteristics of many practical complex planar structures, and has some advant ages over the direct numerical method.
