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.

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.This work presents a triaxially deformed photonic crystal cavity on the SOI substrate, enabling the localization and resonating of photons via pseudomagnetic fields. Through coupling with Si waveguides and leveraging the thermo‐optic effect, electrically tunable pseudo‐magnetism‐induced optical resonances can be achieved in the photonic integrated ...

Empty Justice: Ethnographic Court‐Witnessing in Authoritarian Times
Journal for the Anthropology of North America, Volume 29, Issue 1, Spring 2026.ABSTRACT This article investigates the operations of United States immigration courts ethnographically, examining how law, politics, and bureaucracy converge in the everyday production of immigration adjudication. Based on over 500 h of observation in 36 courtrooms across 11 immigration courts, we document how life‐altering deportation decisions—often ...

Graded-index whispering gallery mode resonators [PDF]
, 2005 Whispering gallery mode optical resonators which have spatially-graded refractive indices. In one implementation, the refractive index spatially increases with a distance from an exterior surface of such a resonator towards an interior of the resonator ...

Tunable Whispering Gallery Mode Resonators for Cavity Quantum Electrodynamics
, 2005 We theoretically study the properties of highly prolate shaped dielectric microresonators. Such resonators sustain whispering gallery modes that exhibit two spatially well separated regions with enhanced field strength.

Low Noise and Drift Reconfigurable Solution‐Processed Chalcogenide Phase Change Metasurfaces
Small Methods, Volume 10, Issue 2, 22 January 2026.Chalcogenide glasses, favored in reconfigurable optoelectronics, rely on costly ultra‐high vacuum‐based PVD methods. A cost‐effective, solution‐based approach to synthesize these materials, producing high‐quality antimony sulfide films with comparable phase change performance are introduced.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing
Sensing and Bio-Sensing Research, 2019 In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle

Abnormal high-$Q$ modes of coupled stadium-shaped microcavities
, 2014 It is well known that the strongly deformed microcavity with fully chaotic ray dynamics cannot support high-Q modes due to its fast chaotic diffusion to the critical line of refractive emission.

Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]
Журнал нано- та електронної фізики, 2010 In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.
