Abstract :
This paper describes the modelling to calculate the induced currents and voltages inside avionics boxes of aircraft due to high intensity radiated electromagnetic fields. The modelling involves several length scales: the wavelength of the exterior electromagnetic field, the diameter of the tubular braid, and the diameter of the wires in the carriers of the braid. The modelling approach is used to calculate the induced voltage at the interfaces of two avionics boxes which are connected to each other by a cable protected by a metal braid.
