Abstract :
The problem of electromagnetic wave scattering from a system of coupled dielectric resonators (DR) placed in a cut off waveguide section has been examined, It has established a common form of characteristic equation for the coupled oscillations, that realizes frequency-symmetrical S matrix parameters. A new structure of the coupling between DRs is indicated as well. Analytical expressions of the power transmission coefficients and experimental investigations of 4 and 5 cylindrical DRs in a microstrip line are given
