摘要: Nanoelectromagnetics problems in nanophotonics and plasmonics in the optical-wavelength regime are concerned in this paper. Very often such problems demand more accurate electromagnetic computation and analysis. A multidomain Legendre pseudospectral time-domain (PSTD) method recently developed and demonstrated to provide high numerical accuracy is utilized to study light interaction with sub-wavelength three-dimensional plasmonic structures and associated plasmonic resonances. With the multidomain technique, the simulation region is partitioned into curvilinear hexahedral subdomains with better fitting to the structural shapes and material interfaces so as to achieve high-accuracy near-field calculations. Light scattering by multiple plasmonic nanospheres and light transmission through a metallic thin film perforated with periodic apertures are investigated with the PSTD analysis.
