Abstract: High-efficiency tunable asymmetric transmission (AT) based on simple-constructed metasurface is highly desired for next generation optical polarization devices. Here, we numerically investigate high-efficiency and frequency-tunable circular AT effect in mid-infrared region by combining simple-shape silicon… read more here.
