2D scattering patterns at the ZBS.
(a) and (b) Scattering patterns are calculated for the same core-shell nanoparticle (Rin = 38 nm, t = 190 nm) but at different wavelengths of λ = 705 nm and λ = 776 nm, respectively. (c) and (d) Scattering patterns are calculated at the same wavelength of λ = 712 nm for core-shell nanoparticles with identical shell thickness of t = 190 nm but different core radii of Rin = 36 nm and Rin = 46 nm, respectively.
