Tunable Asymmetric Transmission via Lossy Acoustic Metasurfaces.
In this study, we show that robust and tunable acoustic asymmetric transmission can be achieved through gradient-index metasurfaces by harnessing judiciously tailored losses. We theoretically prove that the asymmetric wave behavior stems from loss-induced suppression of high order diffraction. We further experimentally demonstrate this novel phenomenon. Our findings could provide new routes to ...
متن کاملGeneration of acoustic helical wavefronts using metasurfaces
In the following, we will consider two cylindrical waveguides separated by a device under test (DUT) of thickness s, the scattering parameters of which will be assessed. A loudspeaker is used to generate sound in the first (incident) waveguide, the second waveguide being closed with an anechoic termination, and four microphones are placed at locations xi at both sides of the interface to measur...
متن کاملReflected wavefront manipulation based on ultrathin planar acoustic metasurfaces
The introduction of metasurfaces has renewed the Snell's law and opened up new degrees of freedom to tailor the optical wavefront at will. Here, we theoretically demonstrate that the generalized Snell's law can be achieved for reflected acoustic waves based on ultrathin planar acoustic metasurfaces. The metasurfaces are constructed with eight units of a solid structure to provide discrete phase...
متن کاملLuminescent hyperbolic metasurfaces
When engineered on scales much smaller than the operating wavelength, metal-semiconductor nanostructures exhibit properties unobtainable in nature. Namely, a uniaxial optical metamaterial described by a hyperbolic dispersion relation can simultaneously behave as a reflective metal and an absorptive or emissive semiconductor for electromagnetic waves with orthogonal linear polarization states. U...
