Abstract

Discontinuities such as tips and edges cause diffracted fields when electromagnetic waves interact with objects. Two-dimensional (2D) wedge with non-penetrable boundaries is a canonical structure which has long been investigated analytically and numerically for the understanding and extraction of diffracted waves. Multiple-diffraction has also been investigated. Here, double tip diffraction is modeled with both finite-difference time-domain and method of moments and reference data are generated.
