Acoustic passive cloaking using thin outer resonators
Lucas Chesnel, Jérémy Heleine, Sergei A. Nazarov
We consider the propagation of acoustic waves in a 2D waveguide unbounded in one direction and containing a compact obstacle. The wavenumber is fixed so that only one mode can prop…

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…
