The characteristics of acoustic wave propagation in rotating solid-state media

2018 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2018
The results of theoretical and experimental researches of acoustic wave propagation into rotating solid-state media are presented. The influence of various rotation directions on wave characteristics is considered. The wave parameters, dependent from rotation velocity, which can be used as an informative signal for angular velocity sensors, are found ...

Steady-state acoustic reflectometry for the reconstruction of solid cylindrical cavities

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002
Acoustic pulse reflectometry has been used in the past for the indirect determination of the cross-section area vs. distance function describing the geometry of solid cylindrical cavities such as the upper airway tract. Excitation pulse bandwidth, noise and system losses are usually the main experimental issues and sources of reconstruction error in ...

Two-Axis Solid-State Microgyroscope on Surface Acoustic Waves

Mekhatronika, Avtomatizatsiya, Upravlenie, 2019
This article focuses on the development of a two-axis solid state micro gyroscope (SMG) on surface acoustic waves (SAW). The described gyroscope belongs to the category of inexpensive sensing elements featuring a high degree of longtime overload stability.

Q-factor of acoustic modes of a solid-state resonator at low temperatures

Measurement Techniques, 2011
The acoustic characteristics of a cylindrical sample made of an aluminum alloy (model of gravity detector) in the course of cooling to temperatures on the order of the boiling point of liquid helium are studied. A specialized cryostat with working chamber having a large volume is presented.

Acoustical measurement of solid state non-linearity: Application to CsCdF3 and KZnF3

Journal of Sound and Vibration, 1983
Abstract Combination of the results of two sets of measurements on the same crystalline samples of CsCdF3 and KZnF3 has made possible the evaluation of the third-order elastic (TOE) constants of these two fluoroperovskites. In the first technique the hydrostatic pressure dependence of the velocity of ultrasonic waves of different propagation and ...

Acoustic intensity modulation of solid-state lasers by means of a rocking mirror

Soviet Journal of Quantum Electronics, 1984
Intensity modulation was produced in ruby and YAG:Nd3+ lasers by varying the angle of inclination of one of the resonator mirrors (rocking the mirror) at an ultrasonic frequency. Modulation occurred at twice the frequency of the excited mirror vibrations, the average intensity of the emission spikes simultaneously increased by a factor of more than 10,

Defect states of acoustic waves in a two-dimensional lattice of solid cylinders

Journal of Applied Physics, 1998
Using the plane-wave expansion method, we study the propagation of acoustic waves through two-dimensional (2D) periodic composites consisting of solid cylinders in air. Defect in those structures create localized states inside the band gaps. We study both single and line defects.
