根据传输线理论，射频波导激光器的电极可近似为无损耗均匀传输线，采用扫频方法，可测量出射频波导激光器电极的重要参数，如特性阻抗、相移常数、相速、分布电感及分布电容等 According to the theory of transmission line, the electrode of RF waveguide laser can be approximated as lossless uniform transmission line. The swept frequency method can be used to measure the important parameters of RF waveguide laser electrode such as characteristic impedance, phase shift constant, phase velocity, distributed inductance and distributed capacitance
