摘　　要：将同轴布喇格反射器的Fortran理论模拟与CST三维电磁仿真软件进行了数值模拟比较.结果表明,当同轴布喇格反射器频率相对偏低且其内外导体相位差为π时,Fortran理论模拟与CST三维电磁仿真软件仿真的结果吻合效果最好.随着频率的不断增加,两者比对的误差会越来越大,当中心频率为250GHz时,由于计算机硬件的限制,CST三维电磁仿真软件将不能模拟出结果.The comparative study of Fortran theoretical simulation with CST of the three-dimensional e- lectromagnetic simulation software is presented. The results show that when the frequency is lower, the Fortran theoretical simulation with CST 3D electromagnetic simulation software simulation results are consistent with the best results when the inner and outer conductors of the coaxial Bragg reflector phase difference is -rr. With the frequency increasing, the error increases. Because of the limit of the comput- er hardwares, three-dimensional electromagnetic simulation software CST will not be able to simulate the results when the frequency reaches 250 GHz .
