Abstract

Frequency selective characteristics of multilayer anisotropic dielectric grating waveguides are analyzed here, having in mind their use as dichroic surfaces in the millimeter waveband. The rigorous formulation described by Costa and Giarola [1993-96] is extended to include biaxial anisotropic dielectrics with their optical axes aligned with the coordinate axes. Numerical results are shown for a sinusoidally varying dielectric constant in the grating. The effect of the dielectric anisotropy square ratio on the resonance anomalies of the diffraction curves is carefully investigated
