Mathematical simulation of electromagnetic wave propagation in inhomogeneous lines

Modeling of wave propagation in inhomogeneous media.

We present a methodology providing a new perspective on modeling and inversion of wave propagation satisfying time-reversal invariance and reciprocity in generally inhomogeneous media. The approach relies on a representation theorem of the wave equation to express the Green function between points in the interior as an integral over the response in those points due to sources on a surface surro...

Wave Propagation in an Inhomogeneous Medium

Wave Propagation and Blocking in Inhomogeneous Media

Wave propagation governed by reaction-diffusion equations in homogeneous media has been studied extensively, and initiation and propagation are well understood in scalar equations such as Fisher’s equation and the bistable equation. However, in many biological applications the medium is inhomogeneous, and in one space dimension a typical model is a series of cells, within each of which the dyna...

Simulation of Wave Propagation over Coastal Structures Using WCSPH Method

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...

Simulation of Wave Propagation

The application of multidimensional digital ltering theory to the simulation of continuous systems with distributed parameters has been treated in various recent contributions. Here, two diierent concepts will be compared, using a lossy transmission line of nite extent as an example. One approach is based on multidimensional wave digital lters, the other on the derivation of a simulating struct...
