简单的电路模型提供了有价值的洞察等离子体共振器的属性。然而，目前还不清楚如何以直观和准确的方式在模型中提取和连接电路元件。在这里，我们提出了一个详细的处理，构建这样的电路的基础上的能量和电荷振荡的考虑。这种方法的准确性和有效性被证明为金纳米棒，并扩展为具有不同间隙尺寸的开口环谐振器，产生良好的直观和定量的协议与完整的电磁模拟。
Simple circuit models provide valuable insight into the properties of plasmonic resonators. Yet, it is unclear how the circuit elements can be extracted and connected in the model in an intuitive and accurate manner. Here, we present a detailed treatment for constructing such circuits based on energy and charge oscillation considerations. The accuracy and validity of this approach was demonstrated for a gold nanorod, and extended for a split-ring resonator with varying gap sizes, yielding good intuitive and quantitative agreement with full electromagnetic simulations.
