Guided modes in a hexagonal periodic graph like domain
Bérangère Delourme, Sonia Fliss
This paper deals with the existence of guided waves and edge states in particular two-dimensional media obtained by perturbing a reference periodic medium with honeycomb symmetry.…
On integrals over a convex set of the Wigner distribution
Bérangère Delourme, Thomas Duyckaerts, Nicolas Lerner
We provide an example of a normalized function such that its Wigner distribution has an integral on the square for…
Electromagnetic shielding by thin periodic structures and the Faraday cage effect
Bérangère Delourme, David P. Hewett
In this note we consider the scattering of electromagnetic waves (governed by the time-harmonic Maxwell equations) by a thin periodic layer of perfectly conducting obstacles. The s…
Trapped modes in thin and infinite ladder like domains. Part 1 : existence results
Bérangère Delourme, Sonia Fliss, Patrick Joly +1
The present paper deals with the wave propagation in a particular two dimensional structure, obtained from a localized perturbation of a reference periodic medium. This reference m…
Existence of guided waves due to a lineic perturbation of a 3D periodic medium
Bérangère Delourme, Patrick Joly, Elizaveta Vasilevskaya
In this note, we exhibit a three dimensional structure that permits to guide waves. This structure is obtained by a geometrical perturbation of a 3D periodic domain that consists o…
On the homogenization of the Helmholtz problem with thin perforated walls of finite length
Adrien Semin, Bérangère Delourme, Kersten Schmidt
In this work, we present a new solution representation for the Helmholtz transmission problem in a bounded domain in with a thin and periodic layer of finite length.…
When a thin periodic layer meets corners: asymptotic analysis of a singular Poisson problem
Bérangère Delourme, Kersten Schmidt, Adrien Semin
The present work deals with the resolution of the Poisson equation in a bounded domain made of a thin and periodic layer of finite length placed into a homogeneous medium. We provi…
