摘要

我们从第一原理出发，推导出了全波状态下开放式频率色散电磁谐振器的一般电路模型。该模型将辐射阻抗的概念扩展到任意外部激励在开放式谐振器中诱导的极化电流密度模式。其基于物理学的元素提供了对散射问题的物理洞察力，并能对任意散射谐振的谐振频率和相关带宽进行有效建模，为纳米光子电路的设计和优化建立了一个强大的平台。我们的研究成果为电磁散射和超快纳米光子学提供了令人信服的前景，简化了具有更快运行速度的纳米谐振器的分析和设计，并概述了基于物理学的时间动力学模型。

First-principles nanocircuit model of open electromagnetic resonators

We derive from first principles a general circuit model for open, frequency dispersive electromagnetic resonators in the full-wave regime. This model extends the concepts of radiation impedance to the polarization current-density modes induced in open resonators by an arbitrary external excitation. Its physics-based elements offer physical insights into the scattering problem and enable efficient modeling of the resonance frequency and associated bandwidth for arbitrary scattering resonances, establishing a powerful platform for the design and optimization of nanophotonic circuits. Our findings offer compelling prospects for electromagnetic scattering and ultrafast nanophotonics, streamlining the analysis and design of nanoresonators with enhanced operational speeds, and outlining a physics-based model of their temporal dynamics.
