Análise teórica de descontinuidade em microfita pelo método da conservação da potência complexa.

Abstract

This work presents the application of the Complex Power Conservation Technique to a class of step discontinuity problems in microfita, using the equivalent waveguide model. It presents the concepts of equivalent waveguide, effective dielotric constant and effective width. The problem of the application of the Complex Power Conservation Technique to the analysis of microfite step discontinuities using the waveguide equivalent model is theoretically formulated, and the propagating and evanescent modes are considered, as well as in the Generalized Spreading Matrix Technique. The discontinuities are considered, for microfita, step and step in cascade. And, theoretically, the problem of eigenvalues ​​for a periodically charged structure is established. As an introduction to the study of periodically loaded microfuge structures, the boundary cases of the periodically loaded parallel plate guide are analyzed. A computer program for the IBM-PC environment is developed and implemented, with which the step discontinuities and cascade step are characterized in microfits. The results obtained are in agreement with those of the specialized literature. Further results are obtained for the boundary cases of the periodically loaded parallel plate guide, and the algorithm QZ was used to determine the auto values. Flowcharts are presented that facilitate the analysis of the implemented program.
