• Absorption of light by a linear chain of gold nanocylinders reveals two resonance peaks. The first peak is associated with the surface plasmon resonance (SPR), and the second additional blue-shifted peak is rationalized by the retarded electromagnetic coupling between the particles in the chain. The dipole electromagnetic coupling leads to constructive interference of light scattered by the particles and results in the additional resonance peak whose wavelength is equal to the interparticle distance. The wavelength and intensity of the additional absorption peak can be tailored by controlling the interparticle distance.
