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

Diffraction of whispering gallery waves by a conjunction line

Journal of Mathematical Sciences, 1999
A nonhomogeneous elastic body with stress-free boundary is considered. The boundary consists of two smooth cylindrical surfaces with continuous tangent plane. The curvature of the boundary is assumed to have a discontinuity on the conjunction line. The behavior of two kinds of transversal surface whispering gallery waves passing through the conjunction

Transverse whispering gallery waves in scattering by elastic cylinders

Ultrasonics, 1990
Abstract The steady-state problem of a normally incident plane acoustic wave scattered by an infinitely long elastic (aluminium) cylinder embedded in a liquid (water) is considered. The far field form function is analysed as a function of x = ka . The modal resonance components are joined into families. It is shown that in the region 0 ⩽ x ⩽ 50,

Radiation field of whispering gallery waves over a concave-convex boundary [PDF]

Journal of Soviet Mathematics, 1982
In this work the wave field arising over a concave-convex reflecting boundary is studied in the Kirchhoff approximation. The field arises as a result of the incidence of whispering gallery waves on an inflection point of the boundary from the concave side.

Whispering-gallery waves in optical fibres

Quantum Electronics, 2002
The 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 mode resonators for millimeter wave radiospectroscopy [PDF]

11th International Conference 'Microwave and Telecommunication Technology'. Conference Proceedings (IEEE Cat. No.01EX487), 2002
The results of a study of the spectral, energy and field characteristics of dielectric resonators having whispering gallery modes in the millimeter range of electromagnetic waves are given. The dielectric resonators such as disks, rings and balls were made on the basis of dielectric materials with low losses (quartz, glass-ceramic, sapphire).

Peculiarities of the excitation of whispering gallery waves in the hemispherical dielectric resonator [PDF]

The Fifth International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter, and Submillimeter Waves (IEEE Cat. No.04EX828), 2004
The carried out investigations of the whispering gallery mode fields in a hemisphere by a local radiant arranged on a mirror and, not having central symmetry, have shown an opportunity of preferred excitation of waves of one type E or H. It allows a little to rarefy a spectrum of excited oscillations, having restricted one of the modes, and more ...

Self-confinement of light whispering gallery waves [PDF]

5th International Workshop on Laser and Fiber-Optical Networks Modeling, 2003. Proceedings of LFNM 2003., 2004
Summary form only given. Among the numerous specific properties of whispering gallery (WG) waves the most important one for the problem considered is that the WG group velocity can be much less than the velocity of light. As a result, the energy density in the WG wave and, consequently, the electric field strength which determines the increase in the ...

Whispering-gallery waves

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.
