Stealth and equiluminous materials for scattering cancellation and wave diffusion
S. Kuznetsova, J. -P. Groby, L. M. Garcia-Raffi +1
We report a procedure to design 2-dimensional acoustic structures with prescribed scattering properties. The structures are designed from targeted properties in the reciprocal spac…
Acoustic response of a rigid frame porous medium slab with a periodic set of inclusions
Jean-Philippe Groby, Armand Wirgin, Laurent De Ryck +1
The acoustic response of a rigid frame porous slab with a periodic set of inclusions is calculated by use of a multipole method. The acoustic properties, in particular the absorpti…
Seismic motion in urban sites consisting of blocks in welded contact with a soft layer overlying a hard half space: II. large and infinite number of identical equispaced blocks
Armand Wirgin, Jean-Philippe Groby
We address the problem of the response to a seismic wave of an urban site consisting of a large and infinite number () of identical, equispaced blocks overlying a soft laye…
Use of specific Green's functions for solving direct problems involving a heterogeneous rigid frame porous medium slab solicited by acoustic waves
Jean-Philippe Groby, Laurent De Ryck, Philippe Leclaire +4
A domain integral method employing a specific Green's function (i.e., incorporating some features of the global problem of wave propagation in an inhomogeneous medium) is developed…
A time domain method for modeling viscoacoustic wave propagation
Jean-Philippe Groby, Chrysoula Tsogka
In many applications, and in particular in seismology, realistic propagation media disperse and attenuate waves. This dissipative behavior can be taken into account by using a visc…
