A Parabolic Equation for Wave Propagation over Porous Structures

Wave Propagation and Scattering in Random Media and Rough Surfaces

Many natural and man-made media such as the atmosphere, oceans, geophysical media, biological media, and composite and disordered materials have random spatial inhomogeneities and vary randomly in time, and these media are called “random media. ’’ Microwaves, optical waves, and acoustic waves propagating in these media experience random fluctuations in space and time, and these fluctuations aff...

Acoustic propagation over periodic and quasi-periodic rough surfaces

Transport noise is an ever present concern in urban areas affecting the quality of life for millions of people. The traditional noise barrier is not always a convenient method of noise control and can divide communities. As a result, other types of barrier have been sought. Considerable interest has been devoted to the use of arrays of vertical cylinders1-3 especially as a result of the publica...

Numerical Modeling of Electromagnetic Wave Propagation Through Bi-Isotropic Materials

As part of the present wave of interest in electromagnetic propagation in complex materials (left-handed, chiral, nonreciprocal, nonlinear, etc.), a special mention may be made to bi-iso‐ tropic materials. After a period of relevance during the nineties [1-4], nowadays they enjoy a renewed interest, because of new fabrication techniques that allow the use of mature tech‐ nologies (printed or in...

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...
