Effective dielectric response of ellipsoid composites in which the dielectric function of the grains have the form of ( the equation is abbreviated ) ) embedded in a host medium is investigated in dilute limit based on perturbative expansion method, and general expressions for the effective linear dielectric function and ( - 1 ) - order nonlinear susceptibility of the two - phase system are derived in this paper
摘要利用微擾展開法討論了任意階弱非線性橢球顆粒復合體系（假定顆粒組分的介電函數隨場變化，表示為（方程式略） ）的有效介電響應，導出了稀釋極限下兩組分橢球顆粒體系的有效線性和有效（ + 1 ）次非線性系數的一般表示式。 -
In this paper a newly develoed helical coordinates is used to make out the solution of electromagnetic fields in the helix gap and calculate dispersion characteristics of tape helix slow wave structure for the first time. strict boundary conditions for magnetic fields are adopted and are treated rigorously by fourier expansion. besides, the radial propagation constant of every layer in the dielectric - loaded region is differentiated. some of practical tape helix slow wave structures have been calculated for dispersion characteristics and the calculated values accord with measured values very well. the authors also compare the calculated results with experiments for different structures by changing tape thickness or other structure parameters and find that the theory in the paper is universal
本文首次運用螺旋坐標系給出了帶狀螺旋線縫隙內的電磁場解，並據此計算了帶狀螺旋慢波結構的色散特性.文中採用了嚴格的邊界條件，並以傅立葉展開進行了嚴格的數學處理.另外還首次對有介質區域內各層的徑向傳輸系數作了區別.本文使用這種方法計算了我們已研製的一些寬帶高功率行波管所用的慢波線結構的色散特性，理論與實驗符合得很好.我們還計算了不同結構參數對色散特性的影響，並與實驗作了對照，發現本文的理論有一定的普適性
