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.

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers
FlexMat, EarlyView.Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Planar Superconducting Whispering Gallery Mode Resonators
, 2013 We introduce a microwave circuit architecture for quantum signal processing combining design principles borrowed from high-Q 3D resonators in the quantum regime and from planar structures fabricated with standard lithography.

Will you teach me? From seriousness to sincerity with apprentice phenomenography
The Australian Journal of Anthropology, EarlyView.Abstract By pushing for adequate modes of conceptualisation, ontological turn theorists have made significant headway in the attempt to take seriously ontological worlds that are typically considered irreconcilable to those of the Western intellectual project.

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 ...

Highly efficient optical power transfer to whispering-gallery modes by use of a symmetrical dual-coupling configuration [PDF]
, 2000 We report that greater than 99.8% optical power transfer to whispering-gallery modes was achieved in fused-silica microspheres by use of a dual-tapered-fiber coupling method.
