Measurement of dispersion characteristic of slow-wave system by microwave network cascade method

In this paper, the microwave network cascade method is proposed for the measurement of dispersion of slow-wave system. Different from the traditional resonance methods, the new method mainly includes three networks, which are the coaxial line to slow-wave system network A, the slow-wave system network B, and the large reflection terminal network C. Theoretical analysis shows that it is easier to measure the dispersion characteristic using the method given in this paper than the traditional resonance method. Moreover, the cold attenuation of slow-wave system can be measured at the same time. The test system is also built in this paper.
