Hyperbolic Metamaterial Devices for Wavefront Manipulation
Laser & Photonics Reviews, 2018 AbstractMetasurfaces have shown great potential to reshape the wavefront of electromagnetic (EM) waves, but transmissive meta‐devices face challenges of low‐efficiency and/or fabrication complexities. Here, an alternative approach to realize high‐efficiency transmission‐mode meta‐devices to control EM wavefronts, based on hyperbolic metamaterial (HMM ...

Reflected wavefront manipulation based on ultrathin planar acoustic metasurfaces. [PDF]
Sci Rep, 2013 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.

Manipulation of acoustic wavefront by gradient metasurface based on Helmholtz Resonators [PDF]
Scientific Reports, 2017 AbstractWe designed a gradient acoustic metasurface to manipulate acoustic wavefront freely. The broad bandwidth and high efficiency transmission are achieved by the acoustic metasurface which is constructed with a series of unit cells to provide desired discrete acoustic velocity distribution. Each unit cell is composed of a decorated metal plate with

Nonreciprocal Pancharatnam-Berry metasurface for unidirectional wavefront manipulations
Optics ExpressOptical metasurfaces employing the Pancharatnam-Berry (PB) geometric phase, called PB metasurfaces, have been extensively applied to realize spin-dependent light manipulations. However, the properties of conventional PB metasurfaces are intrinsically limited by the Lorentz reciprocity.
