Abstract :
We present the far field analysis of a Yagi-Uda antenna array consisting of metal nanorods. The nanorods are described as dipoles taking into account radiation loss, material loss, and detuning. The results suggest that an optical antenna can be realized by gold nanorods of realistic dimensions.
