Scattering of horizontally-polarized shear waves by surface irregularities

Dynamic Soil Sensing via Horizontally-polarized Shear Waves

This paper investigates the feasibility of site characterization via spectral analysis of horizontally-polarized shear (SH) waves as a means to lter the eeects of pore water for saturated soil conditions. Using a multi-layered wave propagation model to simulate the proposed testing connguration revolving around a torsionally vibrating loading plate, it is shown that the use of generalized Love ...

Generation of horizontally polarized shear waves in ferromagnetic materials using magnetostrictively coupled meander‐coil electromagnetic transducers

Laboratory study of polarized scattering by surface waves at grazing incidence. I. Wind waves

AbsfructLaboratory measurements of Ku-band scattering at grazing incidence are presented. This study was motivated by the need to understand the processes which significantly contribute to scattering at grazing incidence. A dual polarized (VV, HH) coherent pulsed Ku-band scatterometer with good temporal resolution (3 ns) was used to obtain Doppler spectra and the absolute cross-section of scatt...

Scattering of Surface Waves

In this chapter the theory of scattering of elastic surface waves is described. Since surface waves are guided along the surface of materials, the scattering properties of surface waves are useful for probing the heterogeneity of the material near the surface as well as perturbations of the free surface. This has applications in the detection of surface defects (Steg and Klemens, 1974) and in s...

Generation of surface waves by shear-flow instability

We consider the linear stability of an inviscid parallel shear flow of air over water with gravity and capillarity. The velocity profile in the air is monotonically increasing upwards from the sea surface and is convex, while the velocity in the water is monotonically decreasing from the surface and is concave. An archetypical example, the ‘double-exponential’ profile, is solved analytically an...
