edge diffraction meaning in Chinese

边缘绕射
边缘衍射

Electromagnetic simulation computation uses three principal scattering mechanisms , including facet contribution , edge diffraction and multi - scattering
本文采用了镜面反射、边缘绕射以及多次反射这三种主要的散射源。
Incremental length diffraction coefficients ( ildc ) is adopted to calculate the contribution of edge diffraction . in order to improve the accuracy of calculation , multi - scattering is discussed , based on the two former contributions and ray - tracing method . geometrical optics ( go ) and physical optics ( po ) are used to calculate the multi - reflection between facets and facets
对于镜面反射采用物理光学法计算其散射贡献，结合基于面元的目标模型的表示，采用离散的积分形式，将面电流积分化简为线积分，简化计算复杂度；对于边缘绕射，运用增量长度绕射系数理论计算目标边缘绕射场；在多次反射中，则以光线跟踪方法为基础，采用几何光学、物理光学相结合的方法分析考虑多次散射场。
