Abstract
This is the first investigation report of a dielectric dot, on a thin gold film, as an antenna in optical frequency range. We examine the effect of various parameters of the dot on its resonance and discuss its emission and receiving properties. The emission from an array of dots is more directional and follows pattern multiplication just like radio antennas. The antenna perspective of tiny dots gives a wonderful analogy with classical electromagnetics which might open a new pathway in the field of nanophotonics. © 2012 Wiley Periodicals, Inc.
