Observation of Two-Dimensional Acoustic Bound States in the Continuum
Marc Martí-Sabaté, Junfei Li, Bahram Djafari-Rouhani +2
The design of devices based on acoustic or optical fields requires the fabrication of cavities and structures capable of efficiently trapping these waves. A special type of cavity…
Bound states in the continuum in circular clusters of scatterers
Marc Martí-Sabaté, Bahram Djafari-Rouhani, Dani Torrent
In this work, we study the localization of flexural waves in highly symmetric clusters of scatterers. It is shown that when the scatterers are placed regularly in the perimeter of…
Abnormal topological refraction into free medium at sub-wavelength scale in valley phononic crystal plates
Linyun Yang, Kaiping Yu, Bernard Bonello +2
In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phon…
Generalized Elastodynamic Model for Nanophotonics
J. V. Alvarez, Bahram Djafari-Rouhani, Dani Torrent
A self-consistent theory for the classical description of the interaction of light and matter at the nano-scale is presented, which takes into account spatial dispersion. Up to now…
Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present the realization of the topological valley-protected zero-order antisymmetric (A0) or symmetric (S0) and zero-order shear-horizontal (SH0) Lamb waves at different domain…
Valley and pseudospin-valley topologically protected edge states in symmetric pillared phononic crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present a symmetric double-sided pillared phononic crystals (PPnCs) that can emulate both quantum spin Hall effect (QSHE) and quantum valley Hall effect (QVHE) by solely imposin…
