| 摘 要： | 运用IPO-MOM混合法分析带旋转叶片腔体的电磁特性。该方法用物理光学迭代法(IPO)计算腔体前端的缓变部分,用基于三角形面元模型的矩量法(MOM)分析含有旋转叶片的腔体终端。在腔体连接口面和开口面上通过Kirchhoff公式实现腔体各部分电磁波的耦合。在开口面上通过对MOM部分进行迭代使得口面内外侧电磁场达到连续。利用该方法分析了高速旋转叶片对电磁波的调制效应。

| Abstract: | A hybrid IPO-MOM method is introduced.The iterative physical optics approach(IPO)is used to treat the front part of the cavity,which slowly varies,and the method of moment(MOM) based on a surface triangle patch model is used to treat the end part of the cavity,which contains rotor blade.At the connected aperture and opened aperture,the electromagnetic waves are coupled with Kirchhoff approximate formula With the iterative MOM,the electromagnetic fields of the inner aperture and outer aperture reach continuum.The effect of rotor-blade modulation on electromagnetic wave is analyzed by the proposed method. |
