Radiation properties of a flanged parallelplate waveguide loaded with an epsilonmu general anisotropic slab
Abstract
In this analysis, the excitation is taken to be either (1) the lowestorder TE or the lowestorder TM (i.e., TEM) waves, or (2) a uniform E or Hpolarized incident plane wave. As a result of the electric (epsilon) and magnetic (mu) anisotropies of the slab, crosspolarization effects are observed. The formulation of the boundaryvalue problem is carried out in the Fouriertransform domain. Previously developed matrix analysis techniques are applied to derive an integral representation of the tangential components of the magnetic field in terms of the tangential components of the electric field at the excitation aperture. After imposing the boundary conditions at the aperture boundary surface, this representation is used in a methodofmoments solution, with the eigenmodes as basis and weighting functions. Numerical results related to the reflection and coupling coefficients as well as the directive diagrams of the structure are presented in graphical form for various cases.
