Table 2.
Maximum pure optical activity (optical activity with ellipticity η ≈ 0) achieved in the structures shown in Figure 1. The table indicates the spectral range where this optical activity is achieved and the associated transmission levels.
| Structure | Spectral range with η = 0 (THz) | Transmission level (%) | Optical activity (degrees/wavelength) at a single frequency where η = 0 (THz) |
