Figure 6

Calculated electric near-field distribution of the NW-antenna system with TE polarized light across the NW plotted in the horizontal plane of the device. (a)–(c) Show the electric field intensity for the wavelength of 465 nm (TE31), 550 nm (TE21) and 680 nm (TE11) for NW with and without the bowtie antennas, respectively.
