Uniqueness Of The Solution

A method is presented of obtaining numerically the surface current density on a perfectly conducting regular or irregular polygonal cylinder when the incident field is either electrically or magnetically polarized (TM or TE) in the axial direction. The surface current density is represented by a sum of continuous modal functions and satisfies the edge conditions. The extended boundary condition is satisfied and the uniqueness of the solution ensured by setting to zero each of the Fourier coefficients of the field around a circle inside the cylinder. Results are presented for a regular triangular cylinder symmetrically illuminated by plane and cylindrical waves.

Transverse Fields

An explicit formula is derived for the surface-current density in terms of the constitutive parameters of the dielectric media adjacent to both sides of the boundary surface. The concepts of the transverse-longitudinal decomposition of electromagnetic fields and the intrinsic impedance for a homogeneous medium are used. The limiting procedure is applied to represent the transverse fields and currents at the interface of two different media.
