Computation of Slope Diffraction by Modified Edge Representation (MER) Equivalent Edge Currents (EECs) Line Integration

摘要

Equivalent edge currents (EECs) line integration to compute the diffiacted field has the advantage of less requirement of computation time and resources. The methods of EECs present some ambiguity in the definition of currents at general edge points which do not satisfy the diffraction law. Modified edge representation (MER) is an unique concept for a complete definition of EEC. The line integration of MER EEC results uniform and accurate fields every-where including geometrical boundaries. Here, MER EECs has been used to compute the diffiacted field from the slope of the incident field. The dipole wave scattering from flat circular disk is considered as the numerical examples.
