提出了一种多层介质中多导体传输线的电容矩阵和电感矩阵的计算方法。导体的数目和介电层的数目是任意的。有些导体的横截面可能是有限的，而另一些则可能是无限小的。导体要么在单个接地面之上，要么在两个平行接地面之间。结合导体-介电界面上的总电荷和介电-介电界面上的极化电荷，提出了自由空间格林函数，得到了该公式。采用矩量法，用脉冲进行展开，用点匹配进行测试。给出了所有导线均为有限截面的情况下的计算结果，以及导线为无穷小细的情况下的计算结果。
A method for computing the capacitance matrix and inductance matrix for a multiconductor transmission line in a multilayered dielectric region is presented. The number of conductors and the number of dielectric layers are arbitrary. Some of the conductors may be of finite cross section and others may be infinitesimally thin. The conductors are either above a single ground plane or between two parallel ground planes. The formulation is obtained by rising a free-space Green's function in conjunction with total charge on the conductor-to-dielectric interfaces and polarization charge on the dielectric-to-dielectric interfaces. The solution is effected by the method of moments using pulses for expansion and point matching for testing. Computed results are given for some cases where all conducting lines are of finite cross section and other cases where they are infinitesimally thin.
