We study transport for a scalar model of Love waves. These waves arise in the propagation of seismic waves whose energy is concentrated in the vicinity of the earth surface. We derive radiative transfer equations from rst principles for the angularly resolved energy density of the Love waves in a simpliied acoustic model. We consider a rough top surface with weak uctuations at the scale of the ...

S U M M A R Y We present a single station method for the determination of Rayleigh wave ellipticity, or Rayleigh wave horizontal to vertical amplitude ratio (H/V) using Frequency Dependent Polarization Analysis (FDPA). This procedure uses singular value decomposition of 3-by-3 spectral covariance matrices over 1-hr time windows to determine properties of the ambient seismic noise field such as ...

We sketch a derivation of abstract scattering theory from the microscopic rst principles deened by Bohmian mechanics. We emphasize the importance of the ux-across-surfaces theorem for the derivation, and of randomness in the impact parameter of the initial wave function|even for an, inevitably inadequate, orthodox derivation. 1 Dedicated to Joel Lebowitz, with love and admiration, for his 70th ...

Surface acoustic wave (SAW) devices based on Rayleigh wave, shear wave, love wave, acoustic plate mode (APM) wave and flexural plate wave have been explored for sensors, actuators and telecommunication applications. An interdigital transducer (IDT) is a metallic comb-like structure fabricated over piezoelectric substrate. SAWs are generated over the substrate by applying electrical signal to th...
