| 摘 要： | 提出考虑传输衰减的高功率微波(HPM)激励模型,基于镀膜透明介质结构设计流程,给出了电磁透射率、反射率计算方法和厚度远低于网格尺寸的薄膜等效处理时域有限差分(FDTD)算法,设计了一种透明导电镀膜的介质屏蔽结构,建立复杂结构与电磁参数的真实三维飞机-飞行员模型,开展了电磁防护分析。仿真结果表明:采用电场幅度最值衰减和防护极限评估防护效果具有良好的工程适用性,且该屏蔽结构在一定载频范围内辐射防护效能好,防护极限高。

| Abstract: | A model of high power microwave(HPM)excitation with propagation attenuation is brought forward.A calculation method of electromagnetic transmission rate and reflectivity is proposed.A finite-difference time-domain(FDTD)film meshing algorithm is set forth.A shielded medium construction planted by transparent conductive film is designed by a new flow.Protection analysis on a 3D plane and pilot model with a scale of 1∶1 against HPM is carried out.The simulation tests show the protection efficiency in the range of carrier frequencies and limit of the shielded construction with incident angle. |
