A metasurface is generally defined as an artificially structured, two-dimensional array of subwavelength elements that collectively control the properties of electromagnetic waves at an …

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. …

Jul 7, 2023 · In recent years, two-dimensional (2D) planar materials, known as metasurfaces, have solved challenging problems encountered by traditional optical devices. Metasurfaces …

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

All metasurface applications involve tradeoffs, sometimes significant. In this talk, I will (imperfectly) review what I find to be the essential physical principles – at a very high level. …

Mar 19, 2025 · By dynamically shaping and directing electromagnetic waves, metasurfaces offer a promising path to overcoming the constraints of conventional wireless systems.

Metasurfaces modulate the amplitude, phase, and polarization of the light. Metasurfaces are used to color filter, metalens, beam modulator, and meta-hologram.

Metamaterials are amongst the advanced materials made up initially with metal structures. However, there is a huge ongoing work on dielectric metasurfaces and metamaterials with the …

These metasurface devices are fabricated using lithography, thin film deposition, and etching, techniques borrowed from semiconductor manufacturing. The production of these devices can …

Jun 16, 2016 · Metasurfaces enable a spatially varying optical response (e.g. scattering amplitude, phase, and polarization), mold optical wavefronts into shapes that can be designed …
