Subwavelength Focussing in Metamaterials Using Far Field Time Reversal,this original approach. Those results are explained in terms of the coherent excitation of subwavelength modes. In particular, we show that a finite size medium consisting of coupled subwavelength resonators, which we call a resonant metalens, supports modes which radiate spatial information of the

Acoustic Surface Waves on Metasurfaces,ments of the acoustic surface waves supported on a simple 2D array of open-ended cavities. We show that the metasurface array supports a highly anisotropic surface wave over a narrow frequency band, which leads to the ‘acoustic beaming’ phenomenon, where acoustic power flow is confined to specific a

Phononic Subsurfaces: Phononic Crystals and Metamaterials for Passive Flow Control, surface and subsequently to their attenuation over the spatial extent of the control region. This entire mechanism is passive and is engineered offline without the need for coupled fluid-structure simulations; only the frequency and modal nature of the flow instability must be known.

Waves Over a Periodic Progressive Modulation: A , Tutorial,. Moreover, the factorization allows to reduce the computational complexity of dispersion diagrams and of long term behaviors. Chosen simulations illustrate salient features of non-reciprocity such as strong left-right biases in the speed and power of propagated waves.
