Design of resonant microcavities: application to optical gyroscopes [PDF]

open access: yes, 2007
We study theoretically and numerically the effect of rotation on resonant frequencies of microcavities in a rotating frame of reference. Cavity rotation causes the shifts of the resonant frequencies proportional to the rotation rate if it is larger than ...

Controlled Brewster Effect in the Scattering of Electromagnetic Waves on Pseudo-Rotating Lattices of Dielectric Resonators

open access: yesVìsnik Nacìonalʹnogo Tehnìčnogo Unìversitetu Ukraïni Kììvsʹkij Polìtehnìčnij Ìnstitut: Serìâ Radìotehnìka, Radìoaparatobuduvannâ, 2023
Various conditions for the occurrence of anomalous scattering, in which most of the power is emitted by the lattice only in the direction of propagation of the incident wave, are analyzed.

Rotational splittings for slow to moderate rotators: Latitudinal dependency or higher order effects in \Omega? [PDF]

open access: yes, 2012
Information about the rotation rate is contained in the low frequency part of power spectra, where signatures of nonuniform surface rotation are expected, as well as in the frequency splittings induced by the internal rotation rate. We wish to figure out

Rotational aerophones

open access: yesThe Journal of the Acoustical Society of America, 2002
Free rotational aerophones such as the bullroarer, which consists of a wooden slat whirled around on the end of a string, and which emits a loud pulsating roar, have been used in many ancient and traditional societies for ceremonial purposes. This article presents an experimental and theoretical investigation of this instrument.
