[en] ANALYSIS OF WAVEGUIDES WITH DIELECTRIC LOADING / [pt] ANÁLISE DE GUIAS DE ONDAS COM CARREGAMENTO DIELÉTRICO

CLAUDIA PEREIRA QUEVEDO 16 August 2006 (has links)
[pt] Neste trabalho são analisados os campos modais em guias circulares contendo em seu eixo um carregamento cilíndrico dielétrico uniforme ou corrugado, identificando propriedades destes campos úteis a aplicações no projeto de ressoadores, filtros e alimentadores. Com o objetivo de apresentar uma aplicação da análise dos guias circulares com carregamento dielétrico, é feita a análise de um ressoador dielétrico cilíndrico apresentando- se sua carta modal relacionando suas freqüências de ressonância com o carregamento dielétrico. / [en] In this work the modal fields for circular waveguides with uniform or corrugated dieletric loads are analysed, and useful properties of these fields to applications such as ressonators, filters and antenna feeders are ecamined. As an application of the analysis of dieletric loaded circular waveguides, an algorithm is developed for the determination of ressonant frequencies of dieletric loaded ressonators, and the modal chart, relating ressonant frequencies to ressonator dimensions, is evaluated.
