Study of SWG-method-of-moment solution of D-volume-integral-equation for plasmonic nano-particles at terahertz frequencies

This paper studies Schaubert-Wilton-Glisson method of moment for D-formulated volume integral equation applied to problems of scattering on plasmonic nanoparticles at THz frequencies. Numerical solution is compared against Mie series solution. Impact of mesh density on solution accuracy is studied. Demostration of convergence properties of pre-conditioned GMRES iterative solution is included in the study.
