Polarization and losses of whispering-gallery waves along twisted trajectories

Journal of the Optical Society of America, 1979
A geometrical optics treatment shows that whispering-gallery waves following twisted trajectories can be in eigenstates of polarization if σ = (radius of curvature × torsion) is a constant. The Jones vectors of these eigenpolarizations are calculated, along with their propagation constants and power attenuation constants.

Millimeter-wave Gunn-diode oscillators based on Whispering Gallery Mode resonators

2015 23rd Iranian Conference on Electrical Engineering, 2015
A millimeter-wave Gunn oscillator based on Whispering Gallery Mode (WGM) resonator is introduced and studied in details. We use full-wave numerical simulations to accurately model the coupling mechanisms and the interactions between various parts of the proposed WGM-based oscillator.

Whispering Gallery wave modes on elastic cylinders

The Journal of the Acoustical Society of America, 1976
We present an analytic and numerical study of Whispering Gallery-type surface- wave modes on solid elastic cylinders imbedded in a fluid. The complex wave numbers of these waves are obtained for the case of high frequencies (ka≳15), including both their attenuation and dispersion curves for the phase velocities. It is shown that there are two different

Whispering gallery dielectric resonators in millimeter wave radiospectroscopy

Fourth International Kharkov Symposium 'Physics and Engineering of Millimeter and Sub-Millimeter Waves'. Symposium Proceedings (Cat. No.01EX429), 2002
The results of study of the spectral, energy and field characteristics of dielectric resonators on whispering gallery modes in millimeter range of electromagnetic waves are given. The dielectric resonators as disks, rings, balls were made on the base of dielectric materials with low losses (quartz, glass-ceramic, sapphire).
