We consider the problem of a plane electromagnetic wave field diffraction on a linear cluster consisting of two plasmonic nanoparticles accounting for the nonlocal effect. The research is based on the mathematical model of the Generalized Non-Local Optical Re-sponse (GNOR). On the basis of the modification of the Discrete Sources Method, a comparative numerical analysis of the scattering characteristics in frequency domain is carried out depending on the geometry of the particles and the distance between them. It has been established that taking account of longitudinal fields has a significant influence both on the extinction cross section and even more on the scattering cross section.
