【Abstract】 Based on FDTD method, the Electromagnetic Compatibility of vehicular communication antennas near to a lossy interface that separates two half-spaces is analyzed in this paper. Contrast to the traditional method, it needs less memory and it is easy to implement. In the end , the FDTD algorithm was used to calculate and analyze the coupling between antennas on one practical vehicle, coupling data was obtained by this method and the results show that this method is feasible for the EMC analysis and design of complex objects.更多还原
