Dynamic Quarter‐Wave Metasurface for Efficient Helicity Inversion of Polarization Beyond the Single‐Layer Conversion Limit (Advanced Optical Materials 2/2022)
Source abstract
Abstract
The metasurface on the back cover (see article number 2101615 by Yosuke Nakata and co-workers) efficiently converts an incident wave with linear polarization (green) into a reflected one with circular polarization (red/blue). Depending on the connection state (represented by red/blue) of the metallic pattern, the rotation direction of circular polarization is switched. The dynamic control of the connection state is realized by leveraging vanadium dioxide. The device is applicable to highly sensitive terahertz detection of chiral molecules that respond differently depending on the handedness of the circular polarization.
