The scattering of flexural waves by a hole in a thin plate traversed by a beam is modeled here by coupling the Kirchhoff-Love and the Euler-Bernoulli theories. A closed form expression is obtained for the transfer matrix (T-matrix) relating the incident wave to the scattered cylindrical waves. For this purpose, a general method has been developed, based on an analogous impedance method for acou...

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 ...

Cross sections and analyzing powers are calculated for the 40Ca( p, 2P)K reaction at proton incident energy of 300 MeV. The t-matrix elements are given by the effective nucleon-nucleon amplitudes of Love-Franey. The optical potentials for distorted waves are calculated by relativistic impulse approximation (RIA). Our calculations are somewhat in poor agreement with experimental data and finally...
