Huygens' principle, Method of Moments, Finite Ele ment Analysis


A recently proposed extended Huygens' principle for scattering objects in lossless waveguide is implemented for dielectric obstacles in waveguide. This technique al lows the coupling of a finite element discretization with a quasi method of moments (MM) surface element ap proach in waveguide. Implementational details for di electric posts are discussed and results presented. The convergence behaviour of a simple test case is investi gated.
