Journal: Scientific Reports
Year: 2025

This paper presents a beam steering technique using optical lenses with a single antenna element, According to changing the illuminator element, the theoretical design of a hemispherical dielectric lens and an inhomogeneous dielectric flat lens modeled with various materials can increase and steer the radiation in a certain direction. The wavelength at which the nanoantenna functions is 1550 nm. The components of the plasmonic nanoantenna are silicon, silicon dioxide, and silver. The light insid
