Аннотация:A modified scheme of the discrete sources method has been applied to investigate the strong interaction between proximal noble metal nanoparticles. The new scheme enables calculation of a near-field enhancement of several orders with a high degree of accuracy. The total field enhancement in between two spheroidal particles and the scattering
cross-section have been analyzed in the frequency domain depending on the separation distance, spheroid aspect ratio, equivolume diameter, and material. In particular, it has been found that spheroids of smaller size can produce larger field enhancement than larger ones. Simulation results demonstrate that it is possible to achieve localized surface plasmon resonance at any desired exciting wavelength by using an appropriate geometrical configuration and material of the coupled spheroids.
