Brief Abstract: The Plasmon resonances of various metallic nanostructures have attracted a great deal of interests recently for its promising applications in light engineering, chemical and biological sensing, waveguiding and etc.  In analogy of how wave functions of atoms interact to form molecules in molecular orbital theory, we present a “plasmon hybridization” picture, which reveals the plasmons of a complex nanostructure can be considered as the hybridization of the parent plasmons of its simpler components. The approach has been applied on investigations of the plasmonic coupling of a nanoparticle and a thin wire, irregular “nanostar” particles, and disk/ring nanocavities. Especially, with the aid of the approach, we studied the plasmonic coherence and interference effect in symmetry-broken systems.
