“…Though the best characteristics of WGM resonators are achieved in optics, millimeter (mm) and sub-millimeter (sub-mm) wave devices have also strong potential. One of the new devices in this range is the laminar WGM resonator [15,16] proposed for making it more sensitive to gaseous or liquid substances surrounding the device and, therefore, facilitating the measurements of dielectric parameters of these substances.…”

“…When measuring characteristics of laminar WGM resonators suspended in free space [16], it was found that their quality factors degrade as compared to those of monolithic devices of the same diameter D and total thickness L. Laminar WGM resonators of low thickness were also more difficult to excite so as, at the thickness below a certain critical value L c , devices were not excited. Provisional measurements of monolithic WGM resonators suspended in free space (more precisely, of a stack of a few cylindrical disks of fused quartz with no air slots between disks) have shown the same tendency, i.e., a stack of small thickness L could not be excited.…”

Measurements of mm-wave excitation spectra of highorder whispering gallery modes in free-space cylindrical disk resonators as functions of resonator thickness have been made. Resonators in the form of tight stacks of thin dielectric disks excited via dielectric waveguides have been used in the experiment. Experimental conditions for the excitation of thin-disk resonators have been found. A simple approach for the modeling of resonator spectra and recovery of dielectric parameters has been proposed.

“…Regarding the choice of the height of the planar DR, expressions were also obtained that determine the minimum sufficient height of the open dielectric disk for the excitation of WGMs in a certain frequency range. The fulfillment of the inequality H ≥ λ d /2 (λ d is a wavelength in a dielectric material of a resonator) is the necessary condition for exciting WGMs in the planar DRs [4][5][6]. This inequality is obtained from an analysis of the physical nature of WGMs [1,3].…”

The spectral and energy characteristics of the tunable thin planar dielectric resonator with the movable metal mirror are researched. It is found that the high-Q HE-polarized whispering gallery modes (WGMs) are effectively excited in such a resonator by the dielectric waveguide. A mode set of the tunable thin planar dielectric resonator depends on the presence of an air gap in its design. Changing the height of the air gap affects the energy characteristics of the tunable thin planar dielectric resonators (DR). Shifting the resonant fields of WGMs from the dielectric disk to the air gap is the reason for this effect. It is shown that at certain heights of the air gap, increasing the unloaded Q-factor of the tunable thin planar DR and improving the excitation efficiency of WGMs in it is achieved.
