Published in 2021 at "Scientific Reports"

DOI: 10.1038/s41598-021-84495-0

Abstract: In this paper, an optical smart multibeam cross dipole nano-antenna has been proposed by combining the absorption characteristic of graphene and applying different arrangements of directors. By introducing a cross dipole nano-antenna with two V-shaped… read more here.

Published in 2019 at "Cogent Engineering"

DOI: 10.1080/23311916.2019.1710428

Abstract: Abstract The cantilever vibrator motion system of a carbon nanotube (CNT) is considered the next step in developing cold cathodes for VHF-band nano-antennas. In cases where a nano-antenna is used in noisy environments, this device… read more here.

Published in 2018 at "Optics express"

DOI: 10.1364/oe.26.012344

Abstract: We propose an all-silicon-based nano-antenna that functions as not only a wavelength demultiplexer but also a polarization one. The nano-antenna is composed of two silicon cuboids with the same length and height but with different… read more here.
