一种新型的平面波加入法在等离子体涂覆目标计算中的应用

Application of a New Method of Setting the Plane-wave in Calculation of the Plasma Coated Targets

为减小目标的雷达散射截面,基于UPML(un-perfectly matched layer)吸收边界条件,比较了新型的分段线性递推平面波加入法和常规的平面波加入法,分析表明新型的平面波加入法能有效的减少电磁波的外泄。将此方法应用于非磁化等离子体涂覆目标的分析,仿真结果表明它可以有效的减少目标的雷达散射截面积,进而验证了该方法的有效性。

In order to reduce the radar cross section（RCS）of target, the novel method of setting the plane-wave and the conventional method are compared based on the un-perfectly matched layer （UPML） absorbing boundary conditions, the analysis indicates that the new method can effectively reduce the energy leakage of the electromagnetic waves. Applying this method to research the non- magnetization plasma coated target, the simulation results confirm the RCS of the target is effectively decreased, which proves the validity of this method.
