Comparison of the measurement method for surface transfer impedance in frequency-domain and time-domain

Aimed to acquire the screening efficiency of the shielded coaxial cable a time-domain measurement method is proposed and a test system based on the triaxial test fixture is designed. By using FFT, time-domain test result can be transformed in to frequency-domain. Comparison shows they fit well with each other. The proposed time-domain test method provides a more straight way to observe the screen efficiency of cables under pulsed fields.
