论文摘要
耦合模式理论（CMT）是将电磁波和散射体之间的相互作用分解为共振及其与功率携带通道的耦合的强大框架。它在纳米素化学的几个谐振，弱耦合的谐振系统中广泛使用，但不能应用于新兴重要性的复杂散射体。我们使用准模式从麦克斯韦方程开发出精确的，从头开始的通用耦合模式理论。我们表示“ QCMT”的准耦合模式理论，可以实现直接的，基于模式的散射矩阵构造，而无需求助于外部求解器或数据。我们认为规范散射体，为此我们表明，CMT模型必然是高度不准确的，而QCMT表现出几乎完美的精度。
Coupled mode theory (CMT) is a powerful framework for decomposing interactions between electromagnetic waves and scattering bodies into resonances and their couplings with power-carrying channels. It has widespread use in few-resonance, weakly coupled resonator systems across nanophotonics, but cannot be applied to the complex scatterers of emerging importance. We use quasinormal modes to develop an exact, ab initio generalized coupled mode theory from Maxwell's equations. This quasinormal coupled mode theory, which we denote "QCMT", enables a direct, mode-based construction of scattering matrices without resorting to external solvers or data. We consider canonical scattering bodies, for which we show that a CMT model will necessarily be highly inaccurate, whereas QCMT exhibits near-perfect accuracy.
