Radiation-Induced Correlation between Molecules Nearby Metallic Antenna Array

Figure 1

(a) Schematic figure of the metallic nanoblocks: we arrange four gold nanoblocks with a small spacing 2.83 nm; the size of each nanoblock is 40 40 4 nm³. (b) The profile of the electric field intensity in the absence of the molecules: the two-way orange arrow indicates the direction of the polarization of the incident field; one can see that the total electric field is strongly enhanced at the spacing and produces “hot spots” for the molecules. (c, d) The profile of the total electric fields is plotted when the direction of the polarization is changed; one can see that the position and the intensity are changed with the direction.
