  • Dielectric waveguide including a tapered wave absorber
    Patent number: 5523727
    Abstract: A dielectric waveguide has a pair of parallel flat metallic plates spaced from each other, a dielectric strip sandwiched between the parallel flat metallic plates, and a wave absorber sandwiched between the parallel flat metallic plates and extending parallel to the dielectric strip. The wave absorber has a tapered portion which is progressively closer to the dielectric strip in a direction away from an inlet end of the wave absorber. The wave absorber has a side surface which may be held in contact with a side surface of the dielectric strip to provide a termination for eliminating reflections of input electromagnetic waves applied to the nonradiative dielectric waveguide, or may be spaced from a side surface of the dielectric strip to provide an attenuator for attenuating the power of input electromagnetic waves applied to the nonradiative dielectric waveguide.
