Scattering of TM Waves by Dielectric Cylinder with Arbitrary Cross Section Partially Covered by a Conductor

부분적으로 도체가 덮인 임의의 단면의 유전체 시린더에 의한 TM 파의 산란현상

The scattering characteristics are analysed for the dielectric cylinder with arbitrary cross section partially covered by thin conductors. The integro differential equations consistant with boundary conditions of conductor and dielectric boundaries are derived by the equivalence principle. They are transformed into matrix equations by moment method. The circular dielectric cylinder covered by conductors at the upper and bottom side of the cylinder is chosen for the numerical example. Current distributions on conductors and scattering cross section by the cylinder are computed for incident wave perpendicular to the conductor plane.
