“…Furthermore, novel active devices can be developed utilizing robust nonlinear optical effects of nanostructured materials. Accordingly, numerous issues of wave propagation including nonlinear effects and surface modes in negative index materials (NIMs) are discussed [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Thus, in this paper, new frontiers are explored to demolish the inherent limitations of scaling for LHM designs to ultraviolet and optical wavelength region exhibiting nonlinear or tunable properties with nanophotonic device application, e.g.…”

In present paper, a tunable left-handed plasmonic nanoantenna is designed to attain ultraviolet emission through a second harmonic generation with a phase harmonic condition. For the devised structure, the dispersion properties and negative values of the magnetic permeability and the electric permittivity show that the designed structure is left-handed for the primary wave (red light) and right-handed for the second harmonic wave (ultraviolet light). The 3D finite-difference time-domain method is employed to reveal its nonpareil skills (i.e. immense left-handed transmission efficiency and far-field spectrum exhibiting directionality). Attained results by numerical calculation for the second harmonic generation are accomplished with finite-difference time-domain analysis. The impact of physical parameters on transmission and dispersion characteristics is also scrutinized. Furthermore, flat lens application for a red light region with a centered wavelength at λ = 650 nm from the guileless design of LHM with no aberration is triumphed. Ultimately, a multifunction left-handed material is designed revealing tremendous potential to amass and abridge future applications in one architecture.
