摘要：

We employ the boundary integral method for the calculation of plasmon resonances in single and coupled metallic nanoparticles. A generic and versatile scheme is developed that allows us to compute the optical properties of arbitrarily shaped nanoparticles embedded in dielectric environments with complex geometry. In the static limit an eigenvalue problem is formulated whose solutions directly provide the plasmon resonances. We present results for spherical, cylindrical, and cubic particles, and discuss the role of coupling and retardation.
