Measured scattering parameters for the coupling of stochastic electromagnetic fields to an unshielded twisted pair cable with a matched termination for different pitch distances

The coupling of stochastic electromagnetic fields into an unshielded twisted double-wire transmission line has been measured in a reverberation chamber. One end of the line features a matched load resistance and is therefore anechoic. With this chosen configuration, the influence of the pitch distance onto the frequency-dependent coupling can be clearly exposed. The measurement results confirm an existing simulation model that is based on transmission line theory and the plane wave integral representation.The raw data of the measurement is saved in text files.Each subfolder is for a different measurement with a different pitch distance or for the coupling between the antennas.The meaning of the examplary filename "alpha_0.0_s11_imag.out" is as follows:- "alpha_0.0" stands for a stirrer angle of 0°- "s_11" means the scattering parameter s_11 (there are also s_12, s_21 and s_22)- "imag" is for the imaginary part- "real" is for the real partThe content of each file is the scattering parameter, where each line stands for a different frequency.The file "alphas.out" contains all the stirrer angles (in °).The file "freqs.out" contains all the frequencies (in Hz).If you encounter any problems or if you have any questions, please contact:Mathias MagdowskiChair for Electromagnetic CompatibilityInstitute for Medical EngineeringOtto von Guericke University Magdeburg, [e-mail] or [e-mail].
