Diffracted and Head Waves Associated With Waves on Nonseparable Surfaces
A theory is presented for computing waves radiated from waves on a smooth surface. With the assumption that attenuation of the surface wave is due only to radiation and not to dissipation in the surface material, the radiation coe cient is derived in terms of the attenuation factor. The excitation coe cient is determined by the reciprocity condition. Formulas for the shape and the spreading of ...

متن کاملDirect calculation of a three-dimensional diffracted field.
We present an approach to calculating the complex amplitude of a three-dimensional (3D) diffracted light field in the paraxial approximation based on a 3D Fourier transform. Starting from the Huygens-Fresnel principle, the method is first developed for the computation of the light distribution around the focus of an apertured spherical wave. The method, with modification, is then extended to tr...
متن کاملSeismic Amplification of Peak Ground Acceleration, Velocity, and Displacement by Two-Dimensional Hills
There are valuable investigations on the amplification effects of the topography on the seismic response in the frequency domain; however, a question is that how one can estimate the amplification of time domain peak ground acceleration (PGA), peak ground velocity (PGV), and peak ground displacement (PGD) over the topographic structures. In this study, the numerical approach has been used for t...
متن کاملDetermining Shear - Wave Velocity from Diffracted S H Waves
Profiles of SH waves diffracted around the core (Sd) for three deep events at stations across North America and the Atlantic (4 = 92 ° to 152 °) are used to determine the properties of the lower mantle in the vicinity of the core-manUe boundary (CMB). The S-wave velocity above the CMB is found to be tic = 7.22 __ 0.1 km/sec, in agreement with gross earth models, but higher than previously repor...
