They are designed to be used within a comprehensive hybrid CAD tool for the efficient analysis of those building blocks for which the fast mode-matching/2-D finite element technique cannot be applied. The advanced algorithms introduced here are doubly higher order, that is higher order basis functions are considered for current/field modeling whereas geometry discretization is performed with triangular/tetrahedral elements of higher polynomial degree.eninfo:eu-repo/semantics/openAccessComputational electromagneticswaveguide structuresmethod of momentsfinite element methodhybrid methodshigher order modelingdyadic Green's functions.530Dissertationurn:nbn:de:gbv:46-00101682-15
