THEORETICAL ANALYSIS FOR DISPERSION CHARACTERISTICS OF ELLIPTIC-GROOVE WAVEGUIDE WITH MODE-MATCHING METHOD

摘要

In this paper, two kinds of elliptic-groove waveguides are presented. One of them has never been studied before. With the help of Mathieu function and mode-matching method, the field components and characteristic equation of the elliptic-groove waveguides are obtained for the first time. Then their dispersion characteristics for the dominant mode i.e.the mode TE^'jare also studied. The gotten conclusions have very important values in theoretical study and actual application for the two kinds of the elliptic-groove waveguides.
