(a) Schematic of grating unit cell used for the simulations, where the different layers, their materials and geometric parameters are shown. (b,c) Simulated surface plots of the norm of the electric field for varying refractive index of the analyte placed on top of silver grating of a (b) aerogel and (c) PDMS substrate.
