| 目的 对带缝金属腔体内连接非线性组件的系统级耦合效应进行分析。方法 在外界电磁激励源的作用下，采用全波混合算法解决腔体内部场强分布问题，并利用高阶FDTD方法求解线缆上的感应电压和电流，得到流入非线性组件的信号，然后建立非线性组件的频域黑箱模型，结合S-参数，得到非线性组件端口的功率响应，最后通过仿真实验验证方法的有效性。结果 通过系统耦合效应分析建模，建立仿真模型，得到了非线性组件的响应曲线。结论 该系统级的耦合效应分析方法可以分析得到非线性组件作为二端口或多端口时的输出功率响应，对系统级的耦合研究具有重要意义。 |

| The paper aims to analyze the system-level electromagnetic effects on nonlinear components in cavity with slots. Under the action of electromagnetic excitation source in the outside world, the hybrid approach was adopted to solve the problem of the filed intensity distribution inside the cavity. The higher-order FDTD method was adopted to solve the cable on the inductive voltage and current to get the signal influx the nonlinear components. And then, the frequency domain black-box model of nonlinear components was established. The power response of nonlinear component ports was obtained in combination with S-parameters. Finally, the validity of the method was verified by simulation. The system-level coupling effect analysis could analyze and obtain the power output response with nonlinear components as a port or multiple ports, and has great significance to the system-level coupling research. |
