SINGLE-RIDGE WAVEGUIDE AND ITS COUPLING TO FABRY-PEROT RESONATORS:PART I THEORETICAL DESCRIPTION

摘要

The functional form of the fields in a single-ridge waveguide are presented. Bethe's small-hole diffraction theory is used to determine the coefficient for coupling from various parts of the guide to a Fabry-Perot resonator. It is shown that frequency-independent coupling over a very broad band is possible, and specific examples are given for the band from 18.0 to 40.0 GHz.
