Electromagnetic Compatibility
Laboratory measurements and simulations of Multiconductor Transmission Lines ended in electronic components. There are datasets corresponding to the following cases:
- one-wire transmission line ended in a diode
- one-wire transmission line ended in an op-amp
- two-wire transmission line where one of the wires is ended in an op-amp (cross-talk study), the other excited by either sin or a square pulse

The attached txt file “cir_bis.txt” is the netlist of the SPICE subcircuit of an EMI filter for dc or single-phase ac applications, valid up to 100 MHz. It can be used in a SPICE-compatible solver (e.g., LTSPICE) for frequency-domain or time-domain simulations. It is a passive black-box macromodel obtained as described in the following paper: S. Negri, G. Spadacini, F. Grassi, and S. A.

This data set is about the measurement of the statistical electromagnetic field coupling to several shielded coaxial cables. The lines are aligned in parallel to a wall of a reverberation chamber. With a vector network analyzer, the coupled voltage between the inner conductor and the cable shield is measured for different stirrer positions over a wide frequency range. For comparison, the coupled current on the cable shield is calculated based on transmission line theory. From the ratio between the inner voltage and the shield current, a coupling resistance can be calculated.
