在本章中，矩形谐振器内的传输线的分析从一端具有两个源/负载的一个导体扩展到沿导体沿着的多个负载以及两个导体之间的相互作用。为此，许多负载被描述为无源小（δ-）源，其相应的电场与来自其他源的场叠加。通过在导体表面上施加总电场的边界条件并对电流应用傅立叶级数展开来找到各个负载中的电流。在谐振器中的两条线的相互作用的计算是基于一个导体的已知描述和二维绿色函数，这发生在电流的解析表达式。该绿色函数分别用于两个导体。然后，借助于叠加原理，推导出线路的各个电流。通过两个例子说明了这些计算过程。
In this chapter, the analysis of transmission lines inside rectangular resonators is extended from one conductor with two sources/loads at the ends to many loads along the conductor and to the interaction between two conductors. To do this, the many loads are described as passive small (δ-) sources, whose corresponding electrical fields superpose with fields from other sources. The currents in the individual loads are found by imposing the boundary condition for the total electrical field on the surface of the conductor and applying a Fourier series expansion for the current. The calculation of the interaction of two lines in the resonator is based on the known description for one conductor and the two-dimensional Green’s function, which occurs in the analytical expressions for the currents. This Green’s function is used for both conductors separately. Then, with the aid of the superposition principle, the individual currents for the lines are derived. These computational procedures are illustrated by two examples.
