DOI: 10.1038/s41598-017-11953-z
Abstract: Polarization is an important property of electromagnetic (EM) wave and different polarization manipulations are required for varied optical applications. Here we report a reconfigurable metasurface which achieves both the polarization conversion and the polarization rotation… read more here.

DOI: 10.1063/1.5046976
Abstract: A birefringent reconfigurable metasurface at visible wavelengths was obtained by combining an Au nanograting metasurface, which shows very high birefringence characteristics in visible light, and a microelectromechanical system actuator. The system was based on the… read more here.

DOI: 10.1364/ao.479520
Abstract: Actively controlling the phase of a terahertz (THz) wave is of great significance for beaming, tunable focusing, and holography. We present a THz phase modulator based on an electrically triggered vanadium dioxide (V O 2)… read more here.
