Robust collimated beaming in 3D acoustic sonic crystals
A. L. Vanel, M. Dubois, C. Tronche +11
We demonstrate strongly collimated beaming, at audible frequencies, in a three-dimensional acoustic phononic crystal where the wavelength is commensurate with the crystal elements;…
Super-localisation of a point-like emitter in a resonant environment : correction of the mirage effect
Lorenzo Baldassari, Alice L. Vanel, Pierre Millien
In this paper, we show that it is possible to overcome one of the fundamental limitations of super-resolution microscopy techniques: the necessity to be in an \emph{optically homog…
Modal approximation for plasmonic resonators in the time domain: the scalar case
Lorenzo Baldassari, Pierre Millien, Alice L. Vanel
We study the electromagnetic field scattered by a metallic nanoparticle with dispersive material parameters in a resonant regime. We consider the particle placed in a homogeneous m…
Mathematical modelling of plasmonic strain sensors
Habib Ammari, Pierre Millien, Alice L. Vanel
We provide a mathematical analysis for a metasurface constructed of plasmonic nanoparticles mounted periodically on the surface of a microcapsule. We derive an effective transmissi…
Modal approximation for strictly convex plasmonic resonators in the time domain: the Maxwell's equations
Habib Ammari, Pierre Millien, Alice L. Vanel
We study the possible expansion of the electromagnetic field scattered by a strictly convex metallic nanoparticle with dispersive material parameters placed in a homogeneous medium…
Acoustic flat lensing using an indefinite medium
M. Dubois, J. Perchoux, A. L. Vanel +10
Acoustic flat lensing is achieved here by tuning a phononic array to have indefinite medium behaviour in a narrow frequency spectral region along the acoustic branch. This is confi…
