Design of a mode converter using thin resonant ligaments
Lucas Chesnel, Jérémy Heleine, Sergei A. Nazarov
The goal of this work is to design an acoustic mode converter. More precisely, the wave number is chosen so that two modes can propagate. We explain how to construct geometries suc…
Modeling of fluid flow in a flexible vessel with elastic walls
V. Kozlov, S. Nazarov, G. Zavorokhin
We exploit a two-dimensional model [7], [6] and [1] describing the elastic behavior of the wall of a flexible blood vessel which takes interaction with surrounding muscle tissue an…
Gaps in the spectrum of two-dimensional square packing of stiff disks
L. D'Elia, S. A. Nazarov
In this paper we investigate via an asymptotic method the opening of gaps in the spectrum of a stiff problem for the Laplace operator in perforated by contiguou…
Design of an acoustic energy distributor using thin resonant slits
Lucas Chesnel, Sergei A. Nazarov
We consider the propagation of time harmonic acoustic waves in a device with three channels. The wave number is chosen such that only the piston mode can propagate. The main goal o…
Band-gap structure of the spectrum of the water-wave problem in a shallow canal with a periodic family of deep pools
Sergei A. Nazarov, Jari Taskinen
We consider the linear water-wave problem in a periodic channel , which is shallow except for a periodic array of deep potholes in it. Motivated by applic…
Abnormal acoustic transmission in a waveguide with perforated screens
Lucas Chesnel, Sergei A. Nazarov
We consider the propagation of the piston mode in an acoustic waveguide obstructed by two screens with small holes. In general, due to the features of the geometry, almost no energ…
