The nano-impedances associated with dielectric and plasmonic nano-cylinders are presented using the Lorenz-Mie theory for plane waves incident upon cylindrical scatterers with radii much smaller than the operating wavelength. The capacitive or inductive behavior is shown to be dependent upon both the polarization of the wave and the angle ξ between the wave vector and the principal axis of the cylinder,...
We outline the differences between the nanocircuits derived from the dipole and the Mie theories, revealing how important a more accurate theory is in the derivation of the nanoimpedances of plasmonic nanospheres.
Preliminary results for gradient forces on optical tweezers, using double-negative (DNG) particles, are presented adopting full electromagnetic theory for focused Gaussian beams, revealing unusual and interesting behaviors that could be exploited in biomedical optics research.
