| 摘 要： | 描述二维电磁场的Ｍａｘｗｅｌｌ方程（ＴＭ模态）可转化为等价的波动方程采用精确控制法计算该波动方程的时间周期角，数值模拟了包括外挂、鼓包以及舱体干扰的复杂气动外形电磁散射场，并计算给出了对应的雷达散射截面（ＲＣＳ）。由于采用了非结构的三角形网格，特别适合计算复杂的实用气动外形。

| Abstract: | An exact controllability approach is used for the calcuation of time periodic solutions of the wave equation, which is proved to be equivalent to the Maxwell equation in two dimensions for the T.M.mode. The numerical results of scattered fields and Radar cross sections(RCS) are presented for complicated aerodynamic shapes with cavity, external obstacle or a slender body. The method presented has the ability to deal with more complicated aerodynamic shapes due to the use of unstructure triangulations |
