Wellentypen auf einzelnen und gekoppelten dielektrischen Wellenleitern

Calculated field line diagrams and dispersion diagrams are used to provide an overview of the characteristics of the lowest nodes in single and coupled image guides with and without substrate and reversed dielectric strip lines. An unsymmetrically coupled pair of waveguides is also considered for the first time. The results are obtained with the help of the orthogonal expansion method.
