EMC ANALYSIS OF ANTENNAS MOUNTED ON ELECTRICALLY LARGE PLATFORMS WITH PARALLEL FDTD METHOD

—In this paper, the Parallel Finite-Difference Time-Domain (FDTD) method based on MPI (Message Passing Interface) is applied to analyze the EMC problems of the electrically large platforms accurately and quickly, which is a full-wave numerical method. The MPI library and domain,decomposition method,are applied to implement the Parallel FDTD method, so that the computation resource is expanded. The method,can analyze the EMC problems by modeling the electrically large platforms accurately. Then the network,theory is introduced to compute,the isolation between antennas combined with the Parallel FDTD method firstly, which avoids the complexity of sweeping frequency and reduce the computing time greatly. Numerical results show that the method,is correct and efficient. Finally, the EMC problems of antennas mounted on electrically large platforms are analyzed and some useful conclusions are obtained.
