A technique to make computer animations representing the propagation of antiplane shear waves in heterogeneous dissipative media is presented. The aim is to develop a useful tool to better investigate...
We present a parallel preconditioning method for the iterative solution of the time-harmonicelastic wave equation which makes use of higher-order spectral elements to reduce pollution error. In partic...
We present an application of the discontinuous Galerkin (DG) method to regional wave propagation. The method makes use of unstructured tetrahedral meshes, combined with a time integration scheme solvi...
Abstract: To seek a deeper understanding of wave propagation on the Schwarzschild spacetime, we investigate the relationship between (i) the lightcone of an event and its caustics (self-intersections)...
This paper deals with the numerical modeling of wave propagation in porous media described by Biot’s theory. The viscous efforts between the fluid and the elastic skeleton are assumed to be a linear f...
The frozen Gaussian approximation provides a highly efficient computational method for high frequency wave propagation. The derivation of the method is based on asymptotic analysis. In this paper, fo...
In 1918 Brouwer considered stability of a heavy particle in a rotating vessel. This was the first demon-stration of a rotating saddle trap which is a mechanical analogue for quadrupole particle traps ...

The velocity of sound in rock is a strong function of pressure, indicating that wave propagation in rocks is very nonlinear. The quasistatic elastic properties of rocks axe hysteretic, possessing disc...
On a Modal Approach to Wave Propagation in a Laterally Homogeneous,Isotropic Halfspace and the Group of Motion of the Euclidean Plane.
In this paper, we applied the CIP (Cubic Interpolated Profile) method to the propagation phenomena of an acoustic wave based on the characteristics. The CIP method is a highly accurate method to solve...
A numerical model is used to simulate the shoreward propagation of a train of periodic borelike surface disturbances in the surf zone over a sloping beach. Turbulence production is included both in th...
An approximate dispersion relation for near-inertial internal waves propagating in geostrophic shear is formulated that includes straining by the mean flow shear. Near-inertial and geostrophic motions...
Coastally trapped Kelvin waves in a model system of a flat half-planar ocean with a high-drag region of width L adjacent to the coast have properties that depend on L, and its drag, D0. For L less tha...
The analysis presented in this paper was inspired by the report that the R/V Polarstern has encountered surface waves of large amplitude hundreds of kilometers inside the ice pack in the Weddell Sea. ...
