摘要：
The discrete-dipole approximation method is implemented with an effective refractive index approximation to obtain surface plasmon resonance modes of metal nanoparticle chains and arrays in a multilayered medium. This fully retarded theoretical model includes the effects of retardation, radiative damping and dynamic depolarization due to the finite size of the nanoparticles. The use of diagonal terms of dyadic Green's functions and different polarizability coefficients along the semi-axes of ellipsoidal nanoparticles provide the complete set of resonance modes. Numerical results show a reasonable agreement with experiment results.
