Hyperbolic Metamaterial Devices for Wavefront Manipulation

Laser & Photonics reviews, 2018
Metasurfaces 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.

Propagation of singularities for gravity-capillary water waves

, 2019
We obtain two results of propagation for the system of gravity-capillary water waves --- first the propagation of oscillations and decay at the spatial infinity and second a microlocal smoothing effect when the initial surface is non-trapping ...

Higher-resolution wavefront sensing based on sub-wavefront information extraction

Frontiers in Physics
The limited spatial sampling rates of conventional Shack–Hartmann wavefront sensors (SHWFSs) make them unable to sense higher-order wavefront distortion.
