Optomechanics with Surface-Acoustic-Wave Whispering-Gallery Modes [PDF]
Physical Review Letters, 2009 A surface acoustic wave (SAW) creates its own high-Q ultra-small volume whispering gallery modes (WGMs), different from usual bulk acoustic WGMs, in an optical dielectric WGM resonator. We show that it is possible to realize an externally controllable, efficient triply-resonant opto-mechanical interaction between two optical WGMs and the SAW WGM and to

Photonic lenses with whispering gallery waves at Janus particles
Opto-Electronic Science, 2022 We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder. These resonances are related to the excited whispering gallery waves caused by truncation. It is a new mechanism of the field localization.

Surface Waves of Rayleigh and Whispering Gallery Type [PDF]
The Journal of the Acoustical Society of America, 1973 Surface waves on smooth curved boundaries consist of an infinite number of modes, the lowest of which may be classified as of “Rayleigh type,” since it tends towards the Rayleigh wave in the limit of vanishing curvature. The others, which correspond to the “Whispering Gallery” modes of Lord Rayleigh, combine to form the lateral wave(s) in the zero ...

Particle acceleration by wave scattering off dielectric spheres at whispering-gallery-mode resonance [PDF]
Physical Review Special Topics. Accelerators and Beams, 2007 The large electromagnetic fields, created in wave scattering near a perfect dielectric sphere at the condition of whispering-gallery-mode resonances, are investigated as driving units for high energy charged particle accelerators.

Optical rogue waves in whispering-gallery-mode resonators [PDF]
Physical Review A, 2014 We report a theoretical study showing that rogue waves can emerge in whispering gallery mode resonators as the result of the chaotic interplay between Kerr nonlinearity and anomalous group-velocity dispersion. The nonlinear dynamics of the propagation of light in a whispering gallery-mode resonator is investigated using the Lugiato-Lefever equation ...

Whispering Gallery Waves in a Neighborhood of a Higher Order Zero of the Curvature of the Boundary
Publications of the Research Institute for Mathematical Sciences, 1989 The paper discusses the behaviour of the high frequency asymptotic solution to the Dirichlet boundary value problem of the reduced wave equation with nonconstant velocity near the boundary where the effective curvature is nonnegative and when it comes closer to the isolated boundary point at which the effective curvature has a higher order zero.

In-Vivo and Ex-Vivo Measurements of Blood Glucose Using Whispering Gallery Modes
Sensors, 2020 The permittivity of blood glucose is not a strong function of its concentration in microwave or millimeter-wave frequencies. Measuring glucose concentrations remains a challenge, particularly in the presence of interference caused by the ambient leaky ...

Far-field phonon coupling in valley metamaterial circuits [PDF]
Nature CommunicationsOn-chip whispering-gallery-mode cavities enable versatile bosonic wave manipulation but typically rely on near-field evanescent coupling. Here we experimentally demonstrate broadband far-field phonon coupling in a valley metamaterial cavity integrated ...

Waveguide for Lamb Waves Based on Whispering-Gallery Mode [PDF]
2018 IEEE International Ultrasonics Symposium (IUS), 2018 We proposed three kinds of waveguides namely straight waveguide, Z-shaped waveguide and Pi-shaped waveguide in an otherwise perfect phononic crystal. We analyzed numerically the transmissivity and the displacement field distribution behind the waveguides.
