The coupled resonances of multiple dielectric resonator structures in metal waveguides

Presented in this paper are the results of theoretical analysis regarding natural oscillations of the systems with a number of coupled spherical dielectric resonators (DR) in flat and rectangular waveguides. It is demonstrated that these systems have frequency isolated high - Q coupling resonances, localized in the region of structure discontinuity. The phenomenon of pulses self-filtration in DR periodic structures is noted.
