From: Influence of the Substrate to the LSP Coupling Wavelength and Strength
a, c, e Scattering spectra of structure A to C when n1 is linearly increased from 1.0 to 1.5. with fixed n2 = 1.5, respectively. b, d, f Scattering spectra of structure A to C when n1 is linearly increased from 1.0 to 1.5, with fixed n2 = 2.5, respectively. The inserts show the relationship between scattering peak wavelengths and n1 for different structures or substrate refractive indices
