In this work, we describe a novel pulse mode shear horizontal-surface acoustic wave (SH-SAW) polymer coated biosensor that monitors rapid changes in both amplitude and phase. The SH-SAW sensors were fabricated on 36 degrees rotated Y-cut X propagating lithium tantalate (36 YX.LT). The sensitivity of the device to both mass loading and visco-elastic effects may be increased by using a thin guidi...

Abstract In this paper, we analyse how the combination of fault zone shape and material properties affects propagation seismic waves in a two-dimensional domain. We focus on SH wave through several faults with different thicknesses bending radii, but theory is easily generalized to three-dimensional case. show density energy released mostly function radius does not depend velocity inside zone.

In this work, a method to reduce the acoustic energy loss has been proposed, and GHz ultra-high ${Q}$ wave resonators based on LiTaO3-on-SiC (LTOSiC) substrate were demonstrated. By modulating ratio of LiTaO3 film thickness interdigit...

I present a finite-difference method for modeling P-SV wave propagation in heterogeneous media. This is an extension of the method I previously proposed for modeling SH-wave propagation by using velocity and stress in a discrete grid. The two components of the velocity cannot be defined at the same node for a complete staggered grid: the stability condition and the P-wave phase velocity dispers...

Management of solitons in media with competing quadratic and cubic nonlinearities is investigated. Two schemes, using rapid modulations a mismatch parameter, the Kerr nonlinearity parameter are studied. For both cases, averaged time wave equations derived. In case management, region parameters where stabilization possible found. it shown that effective χ(2) depends on intensity imbalance betwee...

Abstract The density of a radially inhomogeneous unbounded space is derived as function form. Harmonic dynamics stress the medium with circular cavity investigated by complex variable method. governing equation under incident SH waves in expressed Helmholtz coefficient. It equivalently transformed into standard conformal transformation Then, fields can be proposed. results indicate that changes...

[1] An SH hybrid method is developed for calculating synthetic seismograms involving twodimensional localized heterogeneous structures. The hybrid method is a combination of analytic and numerical methods, with the numerical method (finite difference) applied in the heterogeneous region only and analytical methods applied outside the region. Generalized ray theory solutions from a seismic sourc...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

This paper presents characteristics of quasi-twoday waves (QTDWs) in the mesosphere and lower thermosphere (MLT) between 52 S and 52 N from 2002 to 2011 using TIMED/SABER temperature data. Spectral analysis suggests that dominant QTDW components at mid-high latitudes of the Southern Hemisphere (SH) and the Northern Hemisphere (NH) are (2.13, W3) and (2.04, W4), respectively. The most remarkable...
