Diplexer contains a section of round below cutoff waveguide with a disk, which is anisotropic in a crosscut plane

Diplexer on cylindrical waveguide with anisotropic crystal

Alexander V. Strizhachenko

Abstract


It is proposed the diplexer, which is possible to separate the signals of centimeter wavelength band by frequencies, polarizations, and different waveguide channels, which is characterized by small mass dimension parameters and signal loss in a pass band.


Keywords


diplexer; resonance frequency; cylindrical waveguide; uniaxial crystal
