Wideband polarization-independent anomalous reflection metasurface with multiple resonance modes [PDF]

Journal of Advanced Dielectrics, 2017
An ultra-thin metasurface is proposed to realize wideband polarization-independent anomalous reflection. The sub-wavelength resonator can produce different resonance modes, which are the result of the combined effect of dielectric and the metallic ...

Dielectric Characterization of a Nonlinear Optical Material [PDF]

Scientific Reports, 2014
Batisite was reported to be a nonlinear optical material showing second harmonic generation. Using dielectric spectroscopy and polarization measurements, we provide a thorough investigation of the dielectric and charge-transport properties of this material. Batisite shows the typical characteristics of a linear lossy dielectric.
