This paper deals with a method for the real cables EMC (ElectroMagnetic Compatibility) modeling. This method gives a simple and efficient approach available for the electromagnetic compatibility (EMC). The objective is firstly to take into account the continuous interlacing of the wires. To do that we start from an analytical law of the location of a wire inside the cable. From this law it is possible to construct relations for the characteristic impedance and the wave vector of the real cable. In a second step we compute the cross talk between the wires inside the cable using the relations developed by Vabre. The final equations of the lines can be used both in the time and frequency domain, based on a Branin's circuit. Finally we can study the case of a harness which is a connection of various cables.
