The plasmon hybridization method is generalized to calculate the plasmon modes and optical properties of solid and dielectric-core/metallic-shell particles of geometrical structures that can be described using separable curvilinear coordinates. The authors present a detailed discussion of the plasmonic properties of hollow metallic nanowires with dielectric cores and core/shell structures of oblate and prolate spheroidal shapes. They show that the plasmon frequencies of these particles can be expressed in a common form and that the plasmon modes of the core/shell structures can be viewed as resulting from the hybridization of the solid particle plasmons associated with the outer surface of the shell and of the cavity plasmons associated with the inner surface.
等离子体激元杂交方法被推广用于计算具有可分离曲线坐标描述的几何结构的固体和介质芯/金属壳颗粒的等离子体激元模式及光学性质。作者详细讨论了具有介质芯的中空金属纳米线以及扁球形和长球形的芯/壳结构的等离子体激元性质。他们表明，这些颗粒的等离子体激元频率可以用一种通用形式表示，并且芯/壳结构的等离子体激元模式可被视为由与壳外表面相关的固体颗粒等离子体激元和与内表面相关的腔等离子体激元杂交产生。
