包含几何不连续的结构被指定为四端或双端对波导结构，如果它包括输入和输出区域，每个都以波导传播单模的形式存在。通过将输入和输出波导表示为传输线以及将不连续表示为四端集总常数电路，可以对传播模式进行全面描述。传输线与集总常数电路组成一个四端网络，决定了整个结构的反射、传输、驻波等特性。传输线的定量描述，需要指出其特性阻抗和传播波长；对四端电路的描述，一般需要说明三个电路参数和输入、输出端平面的位置。
A structure that contains a geometrical discontinuity is designated as a four-terminal, or two-terminal-pair, waveguide structure if it comprises an input and an output region each in the form of a waveguide propagating only a single mode. The over-all description of the propagating modes is effected by representation of the input and output waveguides as transmission lines and by representation of the discontinuity as a four terminal lumped-constant circuit. The transmission lines together with the lumped-constant circuit form a four-terminal network that determines the reflection, transmission, standing-wave, etc., properties of the over-all structure. The quantitative description of the transmission lines requires the indication of their characteristic impedance and propagation wavelength; the description of the four-terminal circuit requires, in general, the specification of three circuit parameters and the locations of the input and output terminal planes.
