Abstract

A new design of superior gain assisted double-negative plasmonic nanoantenna to demonstrate nonlinear effects in UV/visible region. Demonstration of near-field transmission spectrum reveals the production of the local-field enhancement up to 10² for half wavelength generation with the incident light wavelength in double nanorod-antenna (DNRA) system and UV/ white light super-continuum generation for the nanoantenna array (NA) system. Negative real values of both permeability (μ) and permittivity (ε) with extremely low imaginary values for visible light is obtained by applying coupled dipole approximation. Near-field and far-field resonance spectrums reveal light amplification and high directionality for the designed nano-antenna.
