Abstract
Nano-antennas are the optical equivalent of antennas that are used to transmit and receive information at radio
frequencies. These antennas have been used in different applications in photonics such as optical imaging, particle
manipulation, bio-sensing, and improvement of the performance of solar cells. In this article we study composite
nano-antennas made of alternating layers of silica and gold. We show that a 50% filling factor leads to a 2.0 times
increase in the electric-field enhancement factor when compared with a pure-gold antenna.
