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…
On the use of Perfectly Matched Layers at corners for scattering problems with sign-changing coefficients
Anne-Sophie Bonnet-Ben Dhia, Camille Carvalho, Lucas Chesnel +1
We investigate in a D setting the scattering of time-harmonic electromagnetic waves by a plasmonic device, represented as a non dissipative bounded and penetrable obstacle with…
A numerical approach for the Poisson equation in a planar domain with a small inclusion
Lucas Chesnel, Xavier Claeys
We consider the Poisson equation in a domain with a small hole of size . We present a simple numerical method, based on an asymptotic analysis, which allows to approximate robus…
