Abstract

Abstract

A method of analyzing the lightning pulse interference into the carbon fiber cabin in airplane is developed based on FDTD. The lightning channel is equivalent to be a linear antenna which is vertical on the conductor ground. Therefore the conception of antenna field partition is used to compartmentalize the lightning field. A plane-wave source can be set up beside cabin with FDTD to analyze far-field effect of lightning field. In near field region a segment of filamentary current which is extended into the Perfectly Matched Layer (PML) reaching the Perfectly Electric Conductor (PEC) boundary outside the PML is set up beside cabin to simulate a part of lightning channel using FDTD. This method avoids the charge effect at the two end-points of the linear current. The FDTD results are accurate compared with analytic results. And then the electric field in the cabin of airplane is calculated in near and far field region using this method, providing the warranty for electromagnetic compatibility design of the carbon fiber cabin.
