Whispering Gallery Effect in Relativistic Optics [PDF]
JETP Letters, 2018 A relativistic laser pulse, confined in a cylindrical target, performs multiple scattering along the target surface. The confinement property of the target results in a very effcient interaction. This proccess, which is just yet another example of the "whispering gallery" effect, may pronounce itself in plenty of physical phenomena, including surface ...

Whispering Gallery States of Antihydrogen
, 2011 We study theoretically interference of the long-living quasistationary quantum states of antihydrogen atoms, localized near a concave material surface. Such states are an antimatter analog of the whispering gallery states of neutrons and matter atoms, and similar to the whispering gallery modes of sound and electro-magnetic waves.

Spherical whispering‐gallery‐mode microresonators
Laser & Photonics Reviews, 2010 AbstractWhispering‐gallery modes (WGM) on a spherical surface were first described by Lord Rayleigh at the beginning of the last century, but only after the invention of laser did they start to have some scientific relevance and only during the last two decades there has been a substantial move towards real devices and practical applications.

Modal domains and selectivity in large square lasers
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsModes in square resonators have C4v symmetry. A special set of modes in these resonators have odd parities and behave like whispering gallery modes. These quasi-whispering gallery modes have high quality factors and exhibit interesting features.

Whispering gallery resonator method for measurementspermittivity
Journal of Telecommunications and Information Technology, 2002 The new method of measuring permittivity is described. The measurements are performed using whispering gallery mode open dielectric resonators. The accuracy is assured by applications of the mode matching method.

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr
Advanced Functional Materials, EarlyView.A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.

Advanced Materials, EarlyView.Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...
