Unlike bulk metamaterials, which achieve unusual properties through three-dimensional structuring, metasurfaces manipulate waves at an interface by imposing abrupt changes in amplitude, phase, or …

Metasurfaces are nanoscale metamaterials that are ultrathin, planar, and smaller than the wavelength of light. Metasurfaces contain nanostructures and subwavelength features that can change the phase, …

Jan 23, 2026 · Metasurfaces and metamaterials (or meta-optics) and their optoelectronic hybrid integration are set to drive the next era of computing, sensing and communications.

What we today call “metasurfaces” represent a convergence of multiple fields of knowledge with different histories and terminologies. In some ways, an evolution rather than a revolution.

Metasurfaces are defined as two-dimensional structures composed of a periodic array of antennas with a thickness smaller than the wavelength of incident electromagnetic waves, which introduce abrupt …

Metasurfaces have unique abilities to block, absorb, concentrate, disperse or guide waves on the surface at a grazing incidence angle and in space at normal and oblique incidence, from microwave …

Jan 29, 2021 · Metasurfaces can be fabricated using standard lithography and nanoimprinting methods, which is easier campared to the fabrication of the counterpart 3 days metamaterials. In this review …

In the following section, we introduce the physical mechanisms, operation superiority, and limitations of several different types of metasurfaces (Table 1).

Apr 1, 2025 · A powerful alternative to traditional, bulky optical components, metasurfaces today enable compact, lightweight, multifunctional applications ranging from imaging systems and augmented …

Jul 5, 2019 · This paper is a critical review of metasurfaces, which are planar metamaterials. Metamaterials offer bespoke electromagnetic applications and novel properties which are not found …
