Simulated transmittance spectra of a silica plate with nanoholes using the 3D-FDTD method. A schematic model for 3D-FDTD simulation (a). Comparison of transmission spectra with and without nanohole structure; the thickness of the silica plate is 150 nm (b).Transmitted spectral variation for different thicknesses of silica plates from 130 to 250 nm (c).
