| Abstract: | We study the optical properties of periodic structures, each of which consists of arrays of subwavelength slits in thick films
that are placed directly against a continuous thin film. We find that the transmittance of the entire system including the
thin film is higher than the transmittance of the isolated thin film alone. Our investigations are performed through numerical
simulations with the Fourier modal method. |
