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

In past decades, terahertz radiation, which locates between microwave and far‐infrared light
in the electromagnetic spectrum, has attracted more and more attention. Various passive …

Intelligent reflecting surfaces can improve the communication between a source and a
destination. The surface contains metamaterial that is configured to “reflect” the incident …

Multiple antenna technologies have attracted much research interest for several decades
and have gradually made their way into mainstream communication systems. Two main …

The use of large arrays might be the solution to the capacity problems in wireless
communications. The signal-to-noise ratio (SNR) grows linearly with the number of array …

Diverse electromagnetic (EM) responses of a programmable metasurface with a relatively
large scale have been investigated, where multiple functionalities are obtained on the same …

The concept of coding metasurface makes a link between physically metamaterial particles
and digital codes, and hence it is possible to perform digital signal processing on the coding …

Metamaterials based on effective media can be used to produce a number of unusual
physical properties (for example, negative refraction and invisibility cloaking) because they …

Traditionally,“metamaterials” have been described by effective medium parameters due to
the subwavelength nature of unit particles. The continuous nature of medium parameters …

Because of their exceptional capability to tailor the effective medium parameters,
metamaterials have been widely used to control electromagnetic waves, which has led to …
