Analysis of field to typical cable networks coupling in reverberation chamber's diffuse field

摘要

For the study of the interference that complex electromagnetic environment coupling to multi-conductor transmission lines, further analysis of the laws of field coupling to lines. The reverberation chamber's chamber electromagnetic environment was simulated by scattering the incident angle of multiple incident waves. The Agrawal coupling theory was used to calculate the current response of the nodes of tree and annular networks. The reverberation chamber, spectrum analyzer, etc. were used to build the experimental system for verification. The result shows that: The "full-radiation" electromagnetic environment built by scattering the scattering the incident angle of multiple incident waves was similar to the field in reverberation chamber. When the transmitted signal is double exponential pulse, as the result of the mismatching loads, the time domain current response would be shock attenuation. The frequency where induced current peak appear had no significant relation with the pipe's length, the amplitude of the inductive current would attenuate with the increasing of frequency.
