Single layer metasurface.
(a) Schematic of metasurface with copper C-shape SRR (r = 1.5 mm, R = 2.5 mm, gap = 0.75 mm, p = 6.5 mm) patterned on FR4 substrate, where two optical axis are vertical ⊥ and parallel ∥ to the gap, respectively. θ is the rotation angle between ⊥ optical axis and x direction. (b) Simulated amplitude transmission of |t21LR| and |t21RR|, which are defined by the electric amplitude ratio between the output LCP or RCP waves and the input RCP wave, respectively. The inset displays the current distribution at the resonant frequency.
