摘要：

We investigate the possibility of directing optical emissions using a Yagi-Uda antenna composed of a finite linear array of nanoparticles. The relevant parameters characterizing the plasma resonances of the nanoparticles are identified and the interaction between the array elements is formulated accordingly. It is shown that the directionality of the optical emission can be observed even in the presence of non-negligible absorption losses in the nanoparticles. We conclude that a finite array of gold nanorods may be sufficient for the realization of a working nano-optical Yagi-Uda antenna.
