Metamaterials are rationally designed composites aiming at effective material parameters
that go beyond those of the ingredient materials. For example, negative metamaterial …

Metamaterials have been characterized by effective medium parameters over the past
decades due to the subwavelength nature of meta-atoms. Once the metamaterials are …

Large intelligent surface (LIS)-assisted wireless communications have drawn attention
worldwide. With the use of low-cost LIS on building walls, signals can be reflected by the LIS …

The recently proposed digital coding metasurfaces make it possible to control
electromagnetic (EM) waves in real time, and allow the implementation of many different …

Harmonic manipulations are important for applications such as wireless communications,
radar detection and biological monitoring. A general approach to tailor the harmonics …

Electromagnetic (EM) metamaterials are artificially engineered media composed of
subwavelength unit cells, which achieve exotic EM properties beyond the limits of natural …

Orbital angular momentum (OAM) beams have demonstrated significant potential in the
fields of communication, imaging and quantum information science. In particular, active OAM …

Large intelligent surface (LIS)-aided wireless communication is a recently proposed concept
with large potential in the fifth-generation (5G) and beyond wireless networks. Taking …

A transmissive metasurface is proposed in this paper. The metasurface consists of three
substrates gaped by air, where the same metallic slot ring is attached to each substrate …
