From zero transmission to trapped modes in waveguides
Lucas Chesnel, Vincent Pagneux
We consider the time-harmonic scattering wave problem in a 2D waveguide at wavenumber such that one mode is propagating in the far field. In a first step, for a given , play…
On well-posedness of time-harmonic problems in an unbounded strip for a thin plate model
Laurent Bourgeois, Lucas Chesnel, Sonia Fliss
We study the propagation of elastic waves in the time-harmonic regime in a waveguide which is unbounded in one direction and bounded in the two other (transverse) directions. We as…
Non reflection and perfect reflection via Fano resonance in waveguides
Lucas Chesnel, Sergei A. Nazarov
We investigate a time-harmonic wave problem in a waveguide. By means of asymptotic analysis techniques, we justify the so-called Fano resonance phenomenon. More precisely, we show…
Trapped modes and reflectionless modes as eigenfunctions of the same spectral problem
Anne-Sophie Bonnet-Ben Dhia, Lucas Chesnel, Vincent Pagneux
We consider the reflection-transmission problem in a waveguide with obstacle. At certain frequencies, for some incident waves, intensity is perfectly transmitted and the reflected…
