From: Point-dipole approximation for small systems of strongly coupled radiating nanorods
The eigenmodes of two horizontal pairs of nanorods (electric dipoles) shown schematically. The red arrows indicate the phase of current oscillations, the shading indicates nanorods in a shared plane. The nanorods are located at \({{\bf{r}}}_{\pm ,1}=[{\lambda }_{0}/2,\pm \,l/2,0]\) and \({{\bf{r}}}_{\pm ,2}=[-{\lambda }_{0}/2,\pm \,l/2,0]\), where \({\lambda }_{0}\) is the resonance wavelength of a single rod. The modes are designated as follows: (a) E1a; (b) E2a; (c) E1s; and (d) E2s.
