    "abstract": "We demonstrate an efficient eigen-decomposition method for analyzing the\nguided modes in metal nanoparticle chains. The proposed method has the\nadvantage of showing the dispersion relation and mode quality simultaneously.\nIt can also separate the material and geometrical properties, so its efficiency\ndoes not depend on the complexity of the material polarizability. The method is\napplied to analyze the guided modes of a single and a pair of metal chains. The\nmore accurate dynamic dipole polarizability typically gives a red-shift\ncompared with the results obtained with the broadly used quasistatic dipole\npolarizability with radiation correction.",
