A review for antenna performance enhancement using metasurface structures [PDF]
Metasurfaces (MS) have recently attracted a lot of attention due to theirability to manipulate electromagnetic characteristics. The metasurfaceis constructed from two-dimensional scatterers (metallic and dielectric)which provide simplicity in fabrication

Review of Metasurfaces and Metadevices: Advantages of Different Materials and Fabrications
Flat optics, metasurfaces, metalenses, and related materials promise novel on-demand light modulation within ultrathin layers at wavelength scale, enabling a plethora of next-generation optical devices, also known as metadevices. Metadevices designed with different materials have been proposed and demonstrated for different applications, and the mass ...

Light‐Controlled Fabrication of Disordered Hyperuniform Metasurfaces
AbstractDisordered hyperuniformity (DHU) is one of the most prominent manifestations of the engineered disorder, which aims to circumvent limitations commonly related to order. Considering the k‐space, isotropic DHU is characterized by an isotropic suppression of scattering for wavenumbers k approaching zero.

Advances in optical metasurfaces: fabrication and applications [Invited]
The research and development of optical metasurfaces has been primarily driven by the curiosity for novel optical phenomena that are unattainable from materials that exist in nature and by the desire for miniaturization of optical devices. Metasurfaces constructed of artificial patterns of subwavelength depth make it possible to achieve flat, ultrathin
