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…
High-Quality Resonances in Quasi-Periodic Clusters of Scatterers for Flexural Waves
Marc Martí-Sabaté, Sébastien Guenneau, Dani Torrent
Multiple scattering theory is applied to the study of clusters of point-like scatterers attached to a thin elastic plate and arranged in quasi-periodic distributions. Two type of s…
Far-field Perfect Imaging with Time Modulated Gratings
Pawel Packo, Dani Torrent
We study the capabilities of time-modulated diffraction gratings as imaging devices. It is shown that a time-dependent but transversally homogeneous slab can be used to make a perf…
Zak's Phase in Non-Symmetric One-Dimensional Crystals
Marc Martí-Sabaté, Dani Torrent
In this work, we derive some analytical properties of Berry's phase in one-dimensional quantum and classical crystals, also named Zak's phase, when computed with a Fourier basis. W…
Edge modes for flexural waves in quasi-periodic linear arrays of scatterers
Marc Martí-Sabaté, Dani Torrent
We present a multiple scattering analysis of robust interface states for flexural waves in thin elastic plates. We show that finite clusters of linear arrays of scatterers built on…
