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…
Analysis of Metal-Dielectric Waveguides with Circular Sectors
Daniel Torrent, Benito Gimeno, Vicente E. Boria +1
The study of metallic corrugated surfaces has recently received strong attention due to their ability to mimic the behaviour of surface plasmons. In this work, this plasmon-like be…
