Analytical and numerical treatment of nonlocal nanoplasmonic resonant effects (Conference Presentation)

Paper Abstract

For the subwavelength plasmonic structures, as their characteristic dimensions are scaling down, it has turned out that the local-response approximation is no longer applicable and more complex models based on the nonlocal response (or even quantum interaction), are required for explaining novel effects, e.g. blue spectral shifts of the resonances, etc. Among these approaches, the longitudinal nonlocal response description based on the linear hydrodynamic model represents the starting point. First, we have concentrated on understanding the interaction and developing simple models capable of predicting the nonlocal response, applicable to simple structures, such as spherical nanoparticles or nonlocal thin layers. Also, as an alternative (and more general) approach, we have considered and developed the extension of the rigorous coupled wave analysis (RCWA) technique capable of treating nonlocal response numerically, for more general both periodic and aperiodic (NonLoc(a)RCWA) structures.
