This work deals with the scattering of acoustic waves by a thin ring that contains regularly
spaced inhomogeneities. We first explicit and study the asymptotic of the solution with …

We consider the homogenized boundary and transmission conditions governing the mean-
field approximations of 1D waves in finite periodic media within the framework of two-scale …

We present a mathematical study of two-dimensional electrostatic and electromagnetic
shielding by a cage of conducting wires (the so-called 'Faraday cage effect'). Taking the limit …

We present algorithms for computing weakly singular and near-singular integrals arising
when solving the 3D Helmholtz equation with curved boundary elements. These are based …

The paper deals with modelling of acoustic waves which propagate in inviscid fluids
interacting with perforated elastic plates. The plate can be replaced by an interface on which …

A surface homogenization method for acoustic waves over thin microstructured surfaces in
the presence of a fluid in a potential flow is presented. Sound hard surfaces are considered …

This work deals with the scattering of electromagnetic waves by a thin periodic layer made of
an array of regularly spaced obstacles. The size of the obstacles and the spacing between …

In this work, we present a new solution representation for the Helmholtz transmission
problem in a bounded domain in R2 with a thin and periodic layer of finite length. The layer …

Quand on s' intéresse à la propagation des ondes dans un milieu périodique à basse
fréquence (ie la longueur d'onde est grande devant la période), il est possible de modéliser …

The paper is devoted to the homogenization of the vibroacoustic fluid-structure interaction
problem in a layer which consists of a perforated plate and a surrounding acoustic fluid. As …
