Electrical and radiation properties of a horn nano-antenna at near infrared frequencies

In this contribution, we present the electrical and radiation properties of a horn nano-antenna working at near infrared frequencies. The proposed nano-antenna consists of an Ag-SiO
₂
-Ag nano-transmission line terminated in a tapered horn. We numerically demonstrate that such a nano-antenna is able to efficiently capture/radiate light at the frequencies of interest. The obtained impedance bandwidth and simulated gain make the proposed nano-antenna a promising solution for telecommunication and energy harvesting applications.
