摘要： 该文是GNES方法在微波定向藕合器电容系数计算中的具体应用,讨论了系数矩阵元的高精密计算和线性方程组维数的选择,分析了主要误差来源,具体计算双圆杆内导体在对称和非对称两种情况下的电容系数,并与零级近似下得到的柱对称模型的解析解作了比较。文中还考察了电容系数随各个几何参数改变的情况,并作了定性解释,最后绘出双椭圆杆内导体的电容系数结果。

Abstract: In this paper, the GNES approach is applied to calculate the capacities of directional couplers. The high precision calculation of matrix elements and accuracy analysis are discussed.The numerical results of its capacities for different configurations(the symmetric and asymmetric,coaxal and non-coaxial double-cylinders and double elliptic cylinders) inner conductors are presented.The practical calculation shows that the GNES approach is successful in high accurate calculation with bigh speed and is the one of the best modern approaches.
