繞射多次反射 的英文怎麼說
中文拼音 [ràoshèduōcìfǎnshè]
繞射多次反射
英文
diffracted multiple-
Electromagnetic simulation computation uses three principal scattering mechanisms, including facet contribution, edge diffraction and multi - scattering
本文採用了鏡面反射、邊緣繞射以及多次反射這三種主要的散射源。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
對于鏡面反射採用物理光學法計算其散射貢獻,結合基於面元的目標模型的表示,採用離散的積分形式,將面電流積分化簡為線積分,簡化計算復雜度;對于邊緣繞射,運用增量長度繞射系數理論計算目標邊緣繞射場;在多次反射中,則以光線跟蹤方法為基礎,採用幾何光學、物理光學相結合的方法分析考慮多次散射場。
