We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

Chiral metamaterials represent a special type of artificial structures that cannot be
superposed to their mirror images. Due to the lack of mirror symmetry, cross-coupling …

We propose a wideband linear polarization converter in transmission mode by bilayer
metamaterial. The polarization converter operates from 0.55 to 1.37 THz with polarization …

We propose a half wave plate in the terahertz region to realize broadband linear polarization
conversion in the reflection mode through anisotropic metamaterials. The structure of this …

In this paper, we proposed a broadband and high-efficient reflective linear–circular​
polarization convertor (LCPC) based on three-dimensional (3D) all-metal anisotropic …

This paper proposes a reconfigurable polarization converter based on a pin diode controlled
active metasurface (AMS). The AMS consists of a thin dielectric substrate and is tuned by …

In this paper, we have studied a practical design of a broadband linear-to-circular polarizer
based on a self-complementary metasurface composed of zigzag-shaped metal strips …

A novel wideband linear-to-circular polarization transmission converter composed by a
cascade of two identical fully metallic frequency selective surfaces (FSSs) separated by an …

Anisotropic impedance surfaces are employed as low-profile and broadband reflectors that
convert orthogonal linear to right-and left-handed circular polarization respectively. By virtue …

In this paper, a multi-functional polarization convertor for terahertz (THz) light composed of a
bilayer wire-split-ring (WSR) structure chiral metamaterial (CMM) was proposed and …
