Exceptional points are spectral singularities in non-Hermitian systems at which two or more
eigenvalues and their corresponding eigenvectors simultaneously coalesce. Originating …

As technology advances, electrical devices such as smartphones have become more and
more compact, leading to a demand for the continuous miniaturization of optical …

Polarization manipulation is a significant issue for artificial modulation of the electromagnetic
(EM) wave, but general mechanisms all suffer the restriction of inherent symmetric properties …

Optical metasurfaces exhibit unprecedented ability in light field control due to their ability to
locally change the phase, amplitude, and polarization of transmitted or reflected light. We …

Recently, there are growing interests in developing super‐resolution metalenses for
applications of focusing and imaging. On one hand, various sub‐diffraction metalenses have …

Benefiting from the excellent capabilities of arbitrarily controlling the phase, amplitude and
polarization of the electromagnetic wave, metasurfaces have attracted much attention and …

Self‐accelerating beams have drawn enormous attentions in optics owing to their
nondiffracting and self‐healing properties. Traditionally, the generation of such beams …

A flat and compact metasurface‐based optical metalens with superior performance can be
widely used for focusing and imaging. However, the realization of a large‐aperture …

The optical sparse aperture approach has been shown to have significant potential in
enlarging the aperture size and enhancing the imaging resolution of metalenses. However …

A class of anisotropic, transmissive electromagnetic metasurfaces is presented, which
