Abstract: In this paper the electromagnetic fields of aircraft current wires are calculated by thefinite element method. The calculation formulation ot the ZOI of AEWN is deduced according to the Maxwell equations. The impedances of current wires with different array forms are calculated, which roughly coincide with normal values. The numerical calculation method is more accurate than the analytic method, which provides an effective method for the design and parameter calculation of AEWN.
