THE EXCITATION OF THE WHISPERING GALLERY MODES IN THE SHIELDED DIELECTRIC RESONATORS BY SLOT-LINE

Abstract

The spectral and energy characteristics of the shielded halfspherical resonator at the forced oscillations mode are investigated experimentally at using of the slot-line. It is shown that the use of slot-line allows maximally rarefying the spectrum of forced oscillations of the shielded resonators with an exceptional allocation of whispering gallery modes and achieving the greatest Q-factor. The experimental investigation and computer simulation show that the slot-line is a channel waveguide having the resonance properties.
