PLASMONIC STRUCTURES FOR IMAGING AND SUPERFOCUSING
Yongqi Fu
Abstract
Superlens for imaging was introduced firstly. Two types of the superlenses were presented: negative refraction-based perfect lens, and metamaterials-based silver superlens. After that, several plasomonic structures such as the subwavelength metallic structures with depth tuning and width tuning, variant periods metallic structures, and funnel-shaped array for beaming and superfocusing were illustrated. A recently developed light source, radial polarization illumination was cited as a new concept of polarization for illumination. Then the radial polarization illumination-based plasmonic structures for superlensing were described. Finally, a nanoplasmonic waveguide for nanofousing was described.
