Diffraction of a plane electromagnetic wave by an elliptic cylinder: The multi-origin technique
Abstract
The diffraction of a plane electromagnetic wave by a perfectly conducting elliptic cylinder is considered. The scattered field is written as a superposition of wave functions satisfying the Helmholtz equation in circular cylindric coordinates with respect to a number of different origins (Multi-origin representation). Then, the boundary conditions are fulfilled using either a simple point-matching technique or using a least-square-error method. The numerical convergence of these techniques is investigated for a number of different origins.
