Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

Becoming invisible at will has fascinated humanity for centuries and in the past decade it
has attracted a great deal of attention owing to the advent of metamaterials. However, state …

Intelligence at either the material or metamaterial level is a goal that researchers have been
pursuing. From passive to active, metasurfaces have been developed to be programmable …

Electromagnetic metasurface cloaks provide an alternative paradigm toward rendering
arbitrarily shaped scatterers invisible. Most transformation-optics (TO) cloaks intrinsically …

Invisibility has been a topic of long‐standing interest owing to the advent of metamaterials
and transformation optics, but still faces open challenges after its tremendous development …

Geometric metasurfaces primarily follow the physical mechanism of Pancharatnam–Berry
(PB) phases, empowering wavefront control of cross‐polarized reflective/transmissive light …

Plasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-
based metamaterials, have attracted progressively increasing attention in recent years …

Optical metasurfaces, capable of manipulating the properties of light with a thickness at the
subwavelength scale, have been the subject of extensive investigation in recent decades …

Regarding miniaturized and integrated systems, a single flat device that possesses
