Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...

The structure freely transmits light with a circular polarization that is opposite to its handedness, while strongly reflecting circularly polarized light with the same handedness. This occurs in ...

“If the chirality is really strong, one circular polarization will experience very slow phase velocity and even finally becomes negative. As a result, the refractive index can be negative even ...

They have published their research in the Physical Review Letters paper "Enabling all-to-circular polarization up-conversion by nonlinear chiral metasurfaces with rotational symmetry." The team's ...

They have published their research in the Physical Review Letters paper “Enabling all-to-circular polarization up-conversion by nonlinear chiral metasurfaces with rotational symmetry”.

Under the illumination of surface waves, these subunits can simultaneously radiate left-handed circular polarization (LCP) and right-handed circular polarization (RCP) components. By controlling ...
