Abstract:   (1206 Views)

In this paper, a chain of silver nanoparticles as a plasmonic waveguide has been investigated. This waveguide when excited by illuminating of its first nanoparticle, depends on polarization of incident light, can support two different plasmonic waves. By using discrete dipole approximation (DDA) method, we have investigated the effect of nanoparticles distance and wavelength of incident light on propagation properties of these plasmonic waves. The obtained results show that plasmonic wave with longitudinal polarization has longer propagation length than the wave with transverse polarization. We have also shown that the propagation length of plasmonic waves and the wavelength which excites the wave with maximum propagation length, can be controlled by adjusting nanoparticles distance.

Keywords: plasmonic waveguide, chain of metal nanoparticles, diffraction limit, discrete dipole approximation
