Thorough analysis of the plasmonic phenomena requires proper account for such effects as size dependent plasmon resonance shifts and intensity changes observed in metal nanoparticles, especially in systems with small feature sizes. Recent theoretical advances, including Generalized Nonlocal Optical Response (GNOR), allow to accurately resolve these effects within the classical electromagnetics, paving the way for implementation of efficient low cost computational techniques. We present a new GNOR-based numerical scheme of the flexible Discrete Sources Method for analysis of light scattering by single plasmonic nanoparticle in the layered medium with rigorous account for both substrate-particle interaction and nonlocal effects.
