The resonant plasmonic properties of small dual rounded nano-scatterers are numerically investigated. A set of Drude-like, silver hexahedral and octahedral structures are studied and compared with a reference spherical particle through a numerical surface integral equation technique. Surface, near field, Poynting field and streamline distributions are presented illustrating novel plasmonic features arising from the complex shapes of the nanoparticles, while several designing rules are described. These qualitative observations can be used appropriately towards sensing, sorting, harvesting, and radiation control applications.
