Frequency Domain Wave Propagation

Frequency domain wave propagation modeling in exploration seismology.

Frequency domain wave propagation. Finite difference frequency domain modeling of viscoacoustic wave propagation in 2d tilted transversely isotropic tti media stéphane operto 1 jean virieux 2 a. A wave vector frequency domain method is presented to describe one directional forward or back ward acoustic wave propagation in a nonlinear homogeneous medium. Ribodetti 1 and j.

Which are used to discretize the viscoacoustic and viscoelastic wave equations describing wave propagation in a porous medium saturated by either a single phase or a two phase compressible inviscid fluid and subject to absorbing boundary conditions. A wave vector frequency domain method is presented to describe one directional forward or backward acoustic wave propagation in a nonlinear homogeneous medium. To achieve this a frequency domain wave equation was developed using previously derived causal dispersion relations.

We can treat the problem as frequency domain. When the electromagnetic field solutions are wave like such as for resonant structures radiating structures or any problem where the effective wavelength is comparable to the sizes of the objects we are working with then the problem can be treated as a wave electromagnetic problem.

Starting from a frequency domain representation of the second order nonlinear acousticwave. Frequency domain modeling of tm wave propagation in optical nanostructures with a third order nonlinear response free pdf download with google download with facebook. This numerical procedure has already been applied to wave propagation in 2d and 3d.
