Abstract
Dispersion characteristics of anisotropic guided-wave structures are analyzed by the edge-element method to eliminate spurious solutions. This approach can be applied to the cases in which the permittivity and permeability matrices are full. An eigenvalue equation which can provide direct solution for the phase constants is also derived when the tensors of the medium can be seperated into transverse and axial components. Numerical examples are presented for longitudinally magnetized, ferrite loaded waveguides and optical waveguides whose optic axis lies in xz- or yz- plane.
