Estudo de Nanoantenas Cornetas Plasmônicas para Aplicações em Banda Ultra Larga

Optical nanoantennas have gained considerable prominence in several works due to their optimal performance for broadband nanophotonics applications. In this research, two plasmonic horned, pyramidal-shaped nanoantennas designed to radiate at the three wavelengths of optical communications: 850 nm (352.9 THz), 1310 nm (229 THz), and 1550 nm (193.5 THz) were proposed. Modeling of the nanoantennas were performed using COMSOL Multiphysics. The proposed nanoantennas showed good performance in terms of directivity, reflection coefficient and gain and hence suitable for applications in optical nanoenlaces.
