| 摘 要： | 对双导体传输线的Taylor模型在频域下的非齐次线性微分方程组,采用常数变异法求得其在边界条件下解的表达式,所求得传输线在终端响应的电压和电流值与BLT方程求得的结果相同。同时,还得到了印刷电路板上的平行双线在外电磁场辐射下终端响应电压的解析表达式,并通过解析解分析得到了不产生干扰电压时的电磁波的入射角度和极化方向。

| Abstract: | In this paper, we use the Constant-transform method to get the solution of the nonhomogeneous linear differential equations from Taylor model for a two-wire line in frequency domain. The solutions for the load current and voltage are equal to the results of the BLT equations. We give an analytic solution to the load voltage in response to an electromagnetic interference on two parallel striplines, and get the incident direction and polarized direction in which the electromagnetic wave dont cause interference voltage on the load of the two parallel striplines. |
