High-Q rectangular cavities and waveguide filters using periodic metalo-dielectric slabs


We obtain the exact solution of Maxwell's equations for the fields in rectangular waveguide or cavity loaded with metalo-dielectric slabs of arbitrary thicknesses and permitivities, placed periodically along the longitudinal direction. For cavity applications, we find significant Q-factor enhancements in the microwave regime, relative to cavities made of… (More)
