High order asymptotics for wave propagation across thin periodic interfaces
نویسندگان
چکیده
This work deals with the scattering of acoustic waves by a thin ring that contains many regularly-spaced heterogeneities. We provide and justify a complete description of the solution with respect to the period and the thickness of the heterogeneities. Our approach mixes matched asymptotic expansions and homogenization theory.

The Propagation of the Waves in Periodic Media Atlarge
Asymptotics at large time of the Green function to the wave equation with periodic coeecients are found. A particular attention is given to its asymptotics near the wave front. It is shown that the spectral band (with number n = 0; 1; 2; ::) of the corresponding Hill operator is associated with a wave having the front velocity c n < 1. Estimates for c n in the terms of the gap lengths, the eeec...

متن کاملSimulation 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...
متن کاملTransmission and Reflection Characteristics of a Concrete Block Wall Illuminated by a TM-polarized Obliquely incident wave
Typically, many of the modern buildings have concrete walls constructed from cinder block walls, that have periodic nature in their relative dielectric constant. This periodic nature excites higher-order Floquet harmonic modes at microwave frequencies, which leads to the propagation of scattered waves along with non-specular directions. Periodic structures exhibit different behaviors when illum...
متن کاملThe Lubrication Approximation for Thin Viscous Films: the Moving Contact Line with a `porous Media' Cut off of Van Der Waals Interactions
We consider the effect of a second order ‘porous media’ [25] term on the evolution of weak solutions of the fourth order degenerate diffusion equation (1) ht = −∇ · (h∇∆h −∇h) in one space dimension. The equation without the second order term is derived from a ‘lubrication approximation’ and models surface tension dominated motion of thin viscous films and spreading droplets [18]. Here h(x, t) ...
