Evanescent wave coupling of whispering gallery modes of a dielectric cylinder
IEE Proceedings, Part J: Optoelectronics, 1993By developing a direct correspondence between a given whispering gallery mode of a dielectric cylinder and a mode of an equivalent waveguide ring resonator, the evanescent wave coupling characteristics of such modes can be simply modelled. This also allows the conditions for resonant excitation of a single whispering gallery mode to be determined.

Whispering-gallery waves in optical fibres
Quantum Electronics, 2002The process of excitation of whispering-gallery waves (WGWs) in optical fibres (microcavities) with the help of a bitapered fibre is analysed. It is shown that useful information on the WGW modes can be obtained from the spectrograms recorded by scanning the exciting-radiation frequency.

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), 2002The 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).

Excitation localization principle for whispering-gallery wave microcavities
Technical Digest. Summaries of Papers Presented at the International Quantum Electronics Conference. Conference Edition. 1998 Technical Digest Series, Vol.7 (IEEE Cat. No.98CH36236), 2002Theory predicts that a tightly focused Gaussian light beam passing outside but near a spherical or cylindrical microcavity will preferentially excite specific cavity resonances depending on its distance to the cavity center. This has been called the localization principle.

Quantum Electronics, 2002
A review of the theory of the natural waves (eigen-modes) in a dielectric sphere is presented. A special attention is paid to the eigenmodes with large radial and azimuthal indices, the so-called whispering-gallery modes. The experimental results of the spectroscopic study of modes in a dielectric sphere are reported.

The creeping and whispering gallery waves on the surface of a transparent body
Journal of Electromagnetic Waves and Applications, 1995The waves propagating on the surface of an arbitrary convex transparent body are studied by the boundary layer method. When the refraction index of the body is high enough. both creeping and whispering gallery type of wave can propagate. The propagation constant are shown to be the same as for an equivalent body described by an impedance boundary ...

Whispering gallery waves localized near circular isobaths in shallow water
The Journal of the Acoustical Society of America, 2019Sound propagation in an area of shallow sea with circular isobaths and the bottom depth increasing towards their curvature center is considered. Such an area could be part of a bay, a lagoon, or a lake with bowl-like bottom relief. The possible formation of whispering gallery waves localized in the vicinity of curved isobaths is considered.
