We suggest an original method utilizing a two beam optical interferometer for the accurate SAW velocity measurements in an anisotropic solid. Namely, two parallel and spatially separated optical beams are diffracted from different points along the pa

Propagation of surface acoustic waves in a system of n anisotropic layers on a semi-infinite anisotropic substrate is considered. In the limit when the wavelength is large compared to the total thickness of the layers, the dispersion relation for sur

To achieve a high stopband rejection in surface acoustic wave (SAW) filters a construction that includes a cascade of some elements (interdigital transducers (IDT) and multistrip couplers (MSC)) is used. In this case each element has to maintain a co

The dynamic properties of nonlinear acoustoelectronic interactions over a wide range of surface acoustic wave (SAW) power for the layered Al/ZnO/SiO 2 /Si were investigated. The existence of a very strong nonlinear dispersion and attenuation of the S

To achieve a high out-of-band rejection in surface acoustic wave (SAW) filters, a construction that includes a cascade of some elements (interdigital transducers (IDT) and multistrip couplers (MSC)) is used. In this case each element must maintain a

Withdrawal weighted (WW) fan-shaped interdigital transducers (IDT) are used to design surface acoustic wave (SAW) filters with a good shape factor, flat passband frequency response (FR), and out-of-band rejection of 50 dB and more. Utilization of "st

The problem discussed here is a realization of frequency responses both with a shape factor of 1.3 or less and with a stopband rejection of 40 dB or more for the most simple and compact configuration of surface acoustic wave (SAW) filters. This SAW f

This paper presents experimental data on the performance of some types of SAW sensors like, biosensor, gas sensor and pressure sensors. It is shown that such parameter, as sensitivity is determined by kind of piezocrystal cut and direction of SAW pro

In this paper we consider two kinds of tag based on surface acoustic wave (SAW) devices and different terminal equipment for registration of these tags. Experimental parameters of tags and an interrogated equipment are considered. >
