Figure 3. (a)–(d) Schematic diagrams of distinctly shaped single plasmonic nanoparticles half immersed in inhomogeneous dielectric background medium. Figures (e)–(h) show the extinction spectra curves of cube-, cylinder-, sphere and ring-shaped nanoparticles for 1.87 refractive index underneath background medium, which show stable Fano-like resonance.
