Novel Directional Nanoantennas for Single-Emitter Sources and Wireless Nano-Links
Figure 6
Comparison of far-field radiation of the dipole emitter embedded in high-index material with and without the nanoantenna. (a) Dipole emitted embedded 2.15 μm below the surface of material, (b) dipole coupled to the nanoantenna, (c) E-field of the dipole emitter, (d) E-field of the coupled dipole-nanoantenna system, (e) far-field radiation pattern of the dipole in high-index material, and (f) far-field of the dipole coupled to the directional nanoantenna. All results are presented at the wavelength 1 μm.
