Figure 8

3D far-field-emission patterns of a dipole source in the vicinity of a bare GNR (diameter 32 nm, length 82 nm). The dipole is located in the Y–Z plane, and it is aligned at a 45° angle from the Z axis. The distance between the dipole and the center of the GNR is varied from 20 to 100 nm. The emission wavelength of the dipole was set to (a) 540 nm and (b) 660 nm. The first frame of each row indicates how the far-field-emission patterns are viewed.
