Influence of the distributed coupling of a waveguide with a disk dielectric resonator with whispering-gallery oscillations on its amplitude-frequency response

The difference between the spectrum of forced oscillations of disk dielectric resonators (when distributed coupling with dielectric waveguide is used) and eigen oscillations of such resonator is considered. The dependence of the amplitude-frequency response of the resonator, excited on the whispering-gallery modes, upon the value of distributed resonator-waveguide coupling and the role of inter-type interaction at purely internal excitation of extraneous mode is investigated.
