Simulation of Lumped Elements in Passive Microstrip Circuit with FDTD Method

本文推导了无源器件在 Yee氏网格中的公式 ,建立了微带电路中含无源器件的不同模型 ,给出了计算结果并与理论值作了比较 ,说明了用时域有限差分法分析计算含集总参数元件的无源微带电路的有效性。

Formulae of computing passive elements in Yee’s grid are given in this paper. We construct different models for microstrip circuit with passive lumped elements. Several numerical results are compared with theoretic results, which confirms the validity of our method.
