(a) Calculated transmission spectra for the metasurface with P = 400 nm and D = 200 nm, providing two resonances at λ = 626 nm and 653 nm. (b) Calculated extinction, scattering, and absorption cross-sections for the a-Si:H nanodisk. Field profiles at (c) λ = 626 nm and (d) λ = 653 nm indicating enhanced H- and E-field in the middle of the nanodisk, indicating a strong MD and ED resonance, respectively.
