Nano/micro object handling with plasmonic antenna structures

The basic concept and its designs

Abstract

We would like to realize a control method of positions and orientations for nano/micro objects such like metallic/dielectric small particles, rods, and wires, which are recently chemically synthesized with various techniques. For this aim, an optical handling method based on electric field gradient forth arisen between metallic antennae by localized plasmon is proposed. The dimensions and gap-distances of the antenna structures are optimally designed with numerical evaluations for target dielectric objects.
