Abstract

Nanorods of noble metals are able to operate as optical nano¬antennas in the visible and IR regimes. The transmissionand the radiation pattern peculiarities of those structures rely in the sizing of single particles and in the engineering of the mutualinteraction among them. When single elements are arranged in an array, an increase of the enhancement of the near field isexpected, along with a significant variation in the far field distribution. In particular, arrays having constant and linearly modulatedlateral gap value (relative distance among each coupled nanoparticle) are compared in order to find the structures that exhibit thebest near¬field enhancement and radiated field pattern
