Analysis of the Robustness of Conventional and Topologically Protected Edge States in Phononic Crystal Plates

Yabin Jin, Daniel Torrent, Bahram Djafari-Rouhani

In this work we theoretically study the interface acoustic states of resonators on a thin plate with topologically protected and conventional designs. Topologically protected inter…

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…

Low-frequency surface plasmon excitations in multicoaxial negative-index metamaterial cables

M. S. Kushwaha, B. Djafari-Rouhani

By using an elegant response function theory, which does not require matching of the messy boundary conditions, we investigate the surface plasmon excitations in the multicoaxial c…

Theory of confined plasmonic waves in coaxial cylindrical cables fabricated of metamaterials

M. S. Kushwaha, B. Djafari-Rouhani

We report on the theoretical investigation of the plasmonic wave propagation in the coaxial cylindrical cables fabricated of both right-handed medium (RHM) [with , ] and…
