Terahertz (THz) waves, situated between the microwave and infrared regions of the electromagnetic spectrum, have drawn ...

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 ...

Terahertz (THz) waves, situated between the microwave and infrared regions of the electromagnetic spectrum, have drawn considerable attention over the ...

These lenses split light with a left-handed circular polarization (LCP) into two focused light beams with left and right-handed circular polarization (RCP).

Scientists have developed a novel technique to transform symmetrical semiconductor particles into intricately twisted, spiral ...
