Resonant and Non-Local Properties of Phononic Metasolids
Daniel Torrent, Yan Pennec, Bahram Djafari-Rouhani
We derive a general theory of effective properties in metasolids based on phononic crystals with low frequency resonances. We demonstrate that in general these structures need to b…
Omnidirectional refractive devices for flexural waves based on graded phononic crystals
Daniel Torrent, Yan Pennec, Bahram Djafari-Rouhani
Different omnidirectional refractive devices for flexural waves in thin plates are proposed and numerically analyzed. Their realization is explained by means phononic crystal plate…
Effective Medium Theory for Elastic Metamaterials in Thin Elastic Plates
Daniel Torrent, Yan Pennec, Bahram Djafari-Rouhani
An effective medium theory for resonant and non-resonant metamaterials for flexural waves in thin plates is presented. The theory provides closed-form expressions for the effective…
Optical absorption of silicon nanowires
Tao Xu, Yannick Lambert, Christophe Krzeminski +6
We report on simulations and measurements of the optical absorption of silicon nanowires (NWs) versus their diameter. We first address the simulation of the optical absorption base…
