我们给出了一个简单直观的图像，一个分子轨道理论的电磁模拟，它描述了任意形状的复杂纳米结构的等离子体激元响应。我们的模型可以理解为由基本几何的纳米结构支撑的基本等离子体的相互作用或“杂交”。作为一个例子，该方法被应用于四层同心纳米壳的重要情况，其中内外纳米壳的等离子体杂化决定了多层纳米结构的共振频率。
We present a simple and intuitive picture, an electromagnetic analog of molecular orbital theory, that describes the plasmon response of complex nanostructures of arbitrary shape. Our model can be understood as the interaction or "hybridization" of elementary plasmons supported by nanostructures of elementary geometries. As an example, the approach is applied to the important case of a four-layer concentric nanoshell, where the hybridization of the plasmons of the inner and outer nanoshells determines the resonant frequencies of the multilayer nanostructure.
