Surface acoustic waves in biosensing applications

Sensors and Actuators Reports, 2021
In this paper, we review the utilization of surface acoustic waves in biosensing applications. A brief background on the theoretical aspects and on the modeling principles for acoustic wave propagation in a liquid medium is provided first.

Investigation of bulk acoustic microwaves excited by an interdigital transducer

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2015
Excitation of bulk and surface acoustic waves with the interdigital transducer (IDT), which is deposited on the surface of a piezoelectric crystal, is widely used in the development of devices in acoustoelectronics and in the design of the microwave ...

Surface Acoustic Waves in Thin Films Nanometrology [PDF]

, 2015
Thin films nanometrology is an emerging field in nanoscience as the synthesis, processing and applications of nanostructured thin films require an in-depth knowledge of their elastic constants. The elastic energy of a surface acoustic wave propagating in

Acoustic-surface-wave filters

Electronics Letters, 1969
Two examples of filters using Rayleigh waves, at the frequencies of 25 MHz and 150 MHz, are described. The shape, almost rectangular, of the frequency response is determined by drawing one transducer.

Temperature-controlled acoustic surface waves

New Journal of Physics, 2016
Conventional approaches to the control of acoustic waves propagating along boundaries between fluids and hard grooved surfaces are limited to the manipulation of surface geometry.

Annular interdigital transducer focuses piezoelectric surface waves to a single point [PDF]

, 2007
We propose and demonstrate experimentally the concept of the annular interdigital transducer that focuses acoustic waves on the surface of a piezoelectric material to a single, diffraction-limited, spot.

Surface acoustic wave frequency comb [PDF]

SPIE Proceedings, 2012
We report on realization of an efficient triply-resonant coupling between two long lived optical modes and a high frequency surface acoustic wave (SAW) mode of the same monolithic crystalline whispering gallery mode resonator. The coupling results in an opto-mechanical oscillation and generation of a monochromatic SAW. A strong nonlinear interaction of

Dispersion of surface acoustic waves in thin films at extreme wavelength-to-thickness ratios [PDF]

JASA Express Letters, 2022
Surface acoustic waves (SAWs) are sensitive to the presence of a layer on the surface of a material, even if this layer is extremely thin compared to their wavelengths. Given the very slow propagation velocities of SAWs compared to electromagnetic waves,
