| Other Titles: | Fortschrittliche Integralgleichungs- und Hybrid-Methoden für die effiziente Analyse allgemeiner Hohlleiter- und Antennen-Strukturen | Authors: | Catina, Valeriu-Ioan | Supervisor: | Arndt, Fritz | 1. Expert: | Arndt, Fritz | Experts: | Silber, Dieter | Abstract: | Three new numerical methods for the calculation of passive waveguide and antenna structures are presented in this work. 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. |
