Figure 9. The extinction spectra and binding force curves of both the near field and far field for three different refractive index values (RI = 1.5, 1.7, 2 respectively) of the three distinct lower background media, respectively. The first and second columns represent the near field, and the third and fourth columns represent the corresponding force curves. Figures (a)–(e) represent the extinction spectra, and figures (f)–(h) represent the binding force curves for the near-field tetramers. Similarly, figures (i)–(l) represent the extinction spectra, and figures (m)–(p) represent the binding force curves for the near-field tetramers.
