Figure 5. Comparison between numerical calculations.

Displaying E_x, E_y, and E_z near-field components at a height of 50 nm above the structures (three left subplots) and the experimentally recorded near-field maps, showing the p-component of the scattered field, E_p (right subplots). The comparison shows that the experimental maps mainly yield the vertical near-field component, E_z. (a,b) correspond to the two enantiomers of the metasurface. The colour scheme for the simulations results is the same as for the experimental results.
