Gold Bow-Tie Shaped Aperture Nanoantenna: Wide Band Near-field Resonance and Far-Field Radiation


In this paper, the optical bow-tie shaped aperture nanoantenna excited by a plane wave is numerically investigated based on the finite integration technique (FIT) where both near-field resonant properties, and far-field radiation characteristics are studied. Different from conventional metallic antennas used in the radio frequency range, gold aperture… (More)
