In this work, we have systematically investigated the polarization and distance effect of Ag-NPs double sphere to localized surface plasmon resonance (LSPR) using metallic nanoparticles simulation based on boundary element approximation. Two way polarizations were applied to Ag-NPs double sphere, in parallel and perpendicular polarizations. LSPR profile generally shifted to red-shift as the diameter of Ag-NPs increased both in parallel and perpendicular polarizations. Concerning the polarization direction, we have found that LSPR shifted to blue-shift as the distance of Ag-NPs double sphere increased in parallel polarization, while LSPR shifted to red-shift in perpendicular polarization. The phenomenon can be explained by the dipole-dipole coupling interaction between Ag-NPs double sphere. The results showed that the LPSR profile was not only affected by the diameter size and the distance of Ag-NPs double sphere but also by the polarization direction.
