In this experiment you will become familiar with diffraction patterns created when a beam of light scatters from objects placed in its path. Such experiments were important historically as they were crucial in establishing the wave nature of light in face of competing theories that described light in terms of geometrical rays of discrete objects. Only a wave theory can give a quantitative expla...
Weakly nonlinear plane waves are considered in hyperelastic crystals. Evolution equations are derived at a quadratically nonlinear level for the amplitudes of quasi-longitudinal and quasi-transverse waves propagating in arbitrary anisotropic media. The form of the equations obtained depends upon the direction of propagation relative to the crystal axes. A single equation is found for all propag...
S U M M A R Y Passive seismic methods using earthquakes can be applied for extracting body waves and obtaining information of subsurface structure. In this study, we retrieve direct and reflected plane waves by applying seismic interferometry to the recorded ground motion from a cluster of regional earthquakes. We apply upgoing/downgoing P/S wavefield decomposition, time windowing, and multidim...
