摘要
文章采用三维时域有限差分(FDTD)方法,对非线性混合电路进行了全波分析,不仅获得不同时刻微带电路平面的电磁场分布图,并且所获得的电压分布图与软件仿真结果高度吻合。由于FDTD是电磁场的全波模拟,所得结果比传统电路模拟精度高且可以得到高频信号激励下微带电路所在平面各个时刻时域内的场解,直接观测到场分布情况,为高频非线性混合电路的特性分析提供了有效依据,同时对研究电磁兼容等问题有重要意义。
The full-wave analysis of nonlinear hybrid circuit is made by finite-difference time-domain （FDTD） algorithm, and the electromagnetic field distribution graph of microstrip circuits at different moments is obtained. The simulation result of FDTD method and that of commercial software are highly consistent. With full-wave simulation of electromagnetic field, its calculation results are more accurate than those of traditional circuit simulations, and the field value and distribution of electro- magnetic field of microstrip circuits at different moments responding to high-frequency signals can be obtained directly, which has important significance for researching the properties of high-frequency nonlinear hybrid circuits and the problems about electromagnetic compatibility and so on.
