为有效计算网络参数对波变量的一阶和二阶灵敏度提供了理论基础。采用了伴随网络的概念。给出了各种元素的一阶灵敏度公式，包括集总和均匀分布元素、有源和无源元素、互反和非互反元素。参数包括电量、几何尺寸和频率。它显示了如何计算与基于波的最小p和极大极小目标函数相关的梯度。并与不需要分析伴随网络的方法进行了比较。展望了利用高效梯度最小化方法在计算机辅助网络设计中的应用。
A theoretical foundation is presented for the efficient computation of first- and second-order sensitivities of networks with respect to network parameters in terms of wave variables. The concept of the adjoint network is used. First-order sensitivity formulas for a wide variety of elements are presented, including lumped and uniformly distributed elements, active and passive elements, and reciprocal and nonreciprocal elements. Parameters include electrical quantities, geometrical dimensions, and frequency. It is shown how gradients related to wave-based least pth and minimax objective functions can be computed. A comparison with a method which avoids the need for analysis of adjoint networks is made. Applications in the computer-aided design of networks using efficient gradient minimization methods are envisaged.
