| 摘 要： | 用时间递推(marching-on in-time,MOT)方法求解了电磁场时域耦合积分方程,计算了均匀介质体的表面等效电流和表面等效磁流,得到时域散射远场并给出了详细推导过程。举例比较了将时域散射用Fourier变化后在频域的RCS和频域直接求得的RCS,以说明该算法的正确性。

| Abstract: | This paper solves electromagnetic coupled integral equations through the marching-on in-time(MOT) method and computes the equivalent electric and magnetic current on the surface of the dielectric bodies,so the far field of transient scattering can be obtained.The detail procedure of algorithm is given.The paper compares the RCS of the results after the Fourier transforms in the examples with the results derived from the frequency field directly.These show that the approach mentioned is available. |
