摘要
采用基于三角形面元模型的矩量法分析研究带旋转叶片腔体的电磁散射特性以及旋转叶片对电磁波的调制影响。通过三维计算机辅助实体建模技术,建立了仿真模型,并实现了腔体与腔内复杂结构表面的网格自动剖分。在腔口面上通过Kirchhoff近似公式实现腔体内外电磁波的耦合。
The effects of rotor-blade modulation on the electromagnetic scattering characteristic of the cavity is analyzed by employing method of moments （MOM） based on the surface triangular patch model. By 3D computer aided modeling technology, a model is constructed and surface mesh of the cavity and complex structure inside the cavity is accomplished automatically, For aperture, the electromagnetic coupling between inside and outside cavity is solved by using Kirchhoff approximate formula.
