Based on a modification of the discrete sources method, a detailed analysis of plasmon resonances of closely located particles is performed. The numerical algorithm makes it possible to calculate the near field with a high degree of accuracy and to trace resonances at which both the cross section and the intensity of the near field increase by several orders of magnitude.
