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 Waves Near Fluid-solid Boundaries
71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009Whispering gallery waves propagated inside fluid along its curved interface with elastic solid are discussed. Asymptotic formula described the wave field is suggested.

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.

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.

High-Q whispering gallery travelling wave resonators for oscillator frequency stabilisation
Proceedings of the 1999 Joint Meeting of the European Frequency and Time Forum and the IEEE International Frequency Control Symposium (Cat. No.99CH36313), 2000Usually a frequency-stabilized standing wave resonator-oscillator incorporating a resonator as a frequency discriminator requires a circulator to separate the injected and reflected wave, A ferrite circulator is a noisy device and can limit the phase noise or frequency stability. Moreover, we show that the noise in a circulator varies, and detailed low

Optical solitons appearing during propagation of whispering-gallery waves
Quantum Electronics, 2003The properties of solitons appearing during the propagation of whispering-gallery waves in a homogeneous glass cylinder are considered. It is shown that such solitons can be used for the light frequency conversion.

Three‐wave mixing in whispering gallery resonators
Laser & Photonics Reviews, 2016AbstractWe review the progress in the development of frequency converters based on three‐wave mixing in whispering gallery resonators (WGRs). The theoretical description, given in a unified notation for all basic processes, reveals that the phase‐matching condition known from conventional devices is replaced by several selection rules and, furthermore,

Terahertz Broadband Whispering-Gallery Mode Gyrotron Backward-Wave Oscillator
IEEE Transactions on Electron Devices, 2019Conventional gyrotron backward-wave oscillators (gyro-BWOs) operate in a low-order mode, e.g., TE $_{0,1}$ mode. As the operating frequency extends to the terahertz (THz) band, the transverse size of low-order mode cavity shrinks, and the power capability is reduced, consequently.
