Fig. 7From: Influence of the Substrate to the LSP Coupling Wavelength and Strengtha, b Schematic diagrams of structure A′ and C′ used for FDTD simulations respectively. c, d Scattering spectra for varying n2 = 1.5, 2.0, and 2.5 of structure A′ and structure C′ respectively. Light is incident normally from air (denoted as black lines) and substrates (denoted as red lines)Back to article page
