Analysis of Coupled Dielectric Resonators by Means of Eigenfrequency Method

Coupled dielectric resonators are analyzed using resonant frequencies of the structures - the eigenfrequency method of coupling coefficient calculations. The method uses simple lumped elements models of coupled dielectric resonators. This models are based upon the mutual coupling concept. It is shown that different resonant modes need to be analyzed with different models. Two and three coupled resonators are investigated. Computations agree very well with the experimental results.
