Plasmonic Nano Antenna¶
This example is taken from Sauvan et al. . The geometry consists of two metallic (Drude model) nano-rods separated by a small gap:
A vertically polarized dipole source is placed in the center of the gap between to two nano-rods.
The Matlab® script
data_analysis/run_scan_wavelength.m provides a scan over the wavelength of the dipole source producing the following plots showing scaled spontaneous emission rates:
The following figure shows the near field intensities in logarithmic scale for the near resonant frequency
