Rectangular Waveguides of the "Hollow Dielectric Canal" Class

Abstract

This paper describes a number of oversized rectangular waveguides with impedance walls, so-called "the hollow dielectric canal waveguides" (EDC-waveguides). Attenuation in HDC-waveguides reduces with decreasing the wavelength, that makes it possible to use these waveguides in millimetre, sub-millimetre and infrared waveranges. Besides, some results of investigation of wave transmission through the regular and irregular HDC-waveguides are considered, and several waveguide components are represented.
