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

We show that the metasurface array supports a highly anisotropic?surface wave?over a narrow frequency?band, which leads to the ‘a(chǎn)coustic beaming’ phenomenon, where acoustic power flow is confined to specific a

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.

Chosen simulations illustrate salient features of non-reciprocity such as strong left-right biases in the speed and power of propagated waves.
