The main purpose of this paper is to establish relations between three iterative numerical methods based on Huygen’s principle that arose almost simultaneously to solve a particular inverse problem. The inverse problem we consider in this paper is to determine the shape of an obstacle from the knowledge of the far field pattern for scattering of(More)
We propose a numerical method for computation of singular electromagnetic fields in a polyhedral non-convex cavity. The method is based on edge conforming elements augmented by special singular functions. The continuity of the total solution is enforced weakly via numerical fluxes. The method can be easily implemented within existing conforming finite(More)
