Abstract

The development of nanotechnologies makes the applications of nonradiative surface plasmons more and more available. The nonradiative surface plasmons also can intensify surface electromagnetic wave, thus, if a nanoparticle can produce surface plasmons we call it as "nano-plasmon-driving intensifier (NPDI)". The distributions of the enhanced electromagnetic wave can be controlled by manipulating multiple NPDIs, our studies show that the enhanced electric field can be focused very well if NPDIs are aligned with parallel to the incident polarization, but it has a premise that the particles should be stationary. The highest enhancement factor of the parallel case can be about 300, it is 15 times than a single NPDI. The amount of surface plasmons of a single NPDI is proportional to the frequency, but the frequency has a minor effect on focusing EM wave.
