NUMERICAL METHOD FOR SOLVING OF THE DIFFRACTION PROBLEM DESCRIBED BY MAXWELL’S EQUATIONS WITH MESOSCOPIC BOUNDARY CONDITIONS

A numerical method for solving the diffraction boundary problem for the system of Maxwell’s equations with mesoscopic boundary conditions has been developed and implemented. It is based on the discrete source method. A numerical analysis of the influence of surface quantum effects on the optical characteristics of plasmonic nanoparticles is carried out. It has been established that surface effects have a significant impact on the field characteristics, and the results differ significantly from the case of volumetric effects.
