Nanoparticle shows unusual characteristics which are different from bulk materials. Over the last decades, synthesis and arrangement methods of nanoparticle with various size and shape have been actively investigated. Especially metallic nanoparticle with sizes smaller than the wavelength of light shows a distinctive characteristic: localized surface plasmon resonance (LSPR). LSPRs are collective electron charge oscillations in metallic nanoparticles, excited by light. However, this resonance characteristic is modified when the metal nanoparticles form an array. In this study, we investigate transition of resonance nature in metal nanoparticle array and corresponding changes in resonance wavelengths and quality factor based on a theoretical model and verify the predictions using finite difference time domain simulations.
