Abstrakt: An exact full-wave analysis of plane-wave scattering by a multilayer nanosphere is proposed. The code is then used to study the behavior of N-layered plasmonic spherical particles. Our primary interest lies in achieving extraordinary scattering or transparency in the infrared regime by judicious pairing of plasmonic materials and control of the core-shell ratio. Numerical results and physical insights of these extraordinary phenomena are provided. [ABSTRACT FROM AUTHOR]
