From: Nano-structured transmissive spectral filter matrix based on guided-mode resonances
Simulated transmission spectra with parameter variation of a fill factor from 0.7 to 0.95, b waveguide layer thickness from 50 nm to 300 nm, c buffer layer thickness from 0 (without buffer layer) to 150 nm, and d metal grating depth from 10 nm to 150 nm. During one parameter variation are others constant. Those original values are P = 500 nm, F = 0.9, W = 100 nm, B = 50 nm and M = 30 nm. The magnetic field distribution Hy at transmission peak wavelengths for the buffer layer thickness of 0 nm (e) and 150 nm (f)
