Simulated transmission amplitudes |T_xx| (upper panels) and |T_xy| (lower panels), for the chiral metamaterials shown in Figure 1d, for linearly polarized incident wave [32]. One can see the cases of silver (black lines) and photoconductive silicon with σ_Si = 1 × 10⁵ S/m (red lines) or 1 × 10³ S/m (green lines) or 2.5 × 10⁻⁴ S/m (blue lines), respectively. The bottom panel shows the corresponding current distributions at the resonance frequencies for σ_Si = 1 × 10³ S/m with E_y linearly polarized incident wave.
