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.…
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…
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…
