THE BIORTHOGONAL MODE THEORY AND APPLICATIONS TO THE ANALYSIS OF WAVEGUIDE DISCONTINUITY PROBLEMS

摘要

The biorthogonal mode formalism will be introduced in this paper,and the application to the analysis problems of metallic posts and irises in rectangular waveguide will be discussed.This modal analysis technique possesses quite a few advantages in comparison with some other analytical and numerical methods,such as faster convergence,physically clear interpretation,and more flexibilities and so forth.To show the effectiveness of this method,some illustrative examples are given.
