Abstract :
The authors describe how anisotropy, with the permittivity tensor involving off-diagonal elements, may be generally formulated by Bergeron´s method. The formulation is discussed for the propagation characteristics of single and parallel striplines on a sapphire substrate with tilted optical axis. To show the distinctive influence of anisotropy on the coupling property between lines, a parallel-line-type directional coupler on such a substrate is analyzed
