Electromagnetic wave scattering on irregular imperfectly conducting structures

Two electromagnetic scattering problems for irregular imperfectly conducting structures are considered. The first one is harmonic dipole field scattering on a bicone at which approximate boundary conditions are fulfilled. The bicone consists of two infinite cones with different surface properties (resistive shells) those depend on distance from vertexes. The other problem is devoted to studying electromagnetic scattering on 3D System of plane angular resistive sectors. Analytical and numerical solutions are obtained. Effects of resistivity are analyzed.
