The Method of Lines for the Analysis of Planar Waveguides Having Uniaxially Anisotropic Substrates

Abstract
The efficient Method of Lines is formulated for the dispersive characterization of planar waveguide structures having uniaxially anisotropic dielectric substrates. This new formulation is exercised upon a configuration of fin-line, one with a substrate bearing an isolated strip opposite a fin. Numerical results follow displaying the importance of heeding anisotropy in modeling.
