Metamaterials are an artificial electromagnetic material composed of periodic/non-periodic
subwavelength micro-/nanostructures, ie meta-atoms. The meta-atom interacts with the …

Metasurface is an artificial material composed of a series of subwavelength structure units
and has unique electromagnetic characteristics. Based on the ability of manipulating the …

The terahertz spectral regime, ranging from about 0.1–15 THz, is one of the least explored
yet most technologically transformative spectral regions. One current challenge is to develop …

Graphene is a new material with a single-layer two-dimensional (2D) honeycomb lattice
structure. It has excellent optical, electrical and mechanical properties, and it is closely …

Surface‐plasmon polaritons are electromagnetic waves propagating on the surface of a
metal. Thanks to subwavelength confinement, they can concentrate optical energy on the …

Metasurfaces solve the lack of materials in the terahertz (THz) band and control precisely the
amplitude, phase, polarization, and transmission characteristics of THz waves, providing an …

Over the last 20 years, thin and lightweight optical elements have become very desirable,
especially for the terahertz (THz) range. Reduction of the volume of optical elements …

Indium–tin–oxide nanowhiskers were employed as transparent electrodes in a liquid-crystal
terahertz phase shifter. Transmittance of the device was as high as∼ 75%. Phase shift …

Ultrafast terahertz spectroscopy accesses the dark excitonic ground state in resonantly
excited (6, 5) single-walled carbon nanotubes via internal, direct dipole-allowed transitions …

Tunability in metamaterials has added a new dimension to the functionality and application
scope for light–matter interaction in the subwavelength regime. Microelectromechanical …
