Examples
- A new . algorithm to search the regions encircled by arbitrary lines and arcs
寻找任意线段和圆弧围成区域的一种算法 - " 400 , 000 is perceived as representing the dividing point between contraction and stability in the labor market , but really it ' s an arbitrary line in the sand , " said morgan stanley economist bill sullivan
确实使人感到就业情况略有改善。但是人们为什麽总是认为40万是一个劳动力市场收缩或稳定的重要的分界线？ - Then the solving procedures of these bies by the rwg functions based moment method are elaborated , and the method of modeling complex objects built of arbitrary line , surface and volume structures is developed . in order to solve realize antenna and circuit problems , methods of adding excitations and concentrated loadings with moment method are deceloped , and matrix pencil ( mp ) method is used to deembeded the s prameters of antennas and circuits from the computed current distribution . some numerical results of practical complex antenna and scattering problems are presented to illustrate the veracity and effectiveness of the method
在第一部分中,首先从电磁场的基本理论出发,基于等效原理和边界条件以统一的方法建立了用于分析金属、介质及金属与介质混合结构的边界积分方程,并归纳和比较了各类积分的适用范围和优缺点;在此基础上,给出了使用基于rwg函数的矩量法求解各种边界积分方程的一般过程;研究了具有任意线、面、体组成的复杂结构的电磁建模方法,并给出了各种多面连接情况下基函数和未知量的选取方法;研究了使用矩量法分析电路、天线问题时集总元件和激励源的处理方法,并基于矩阵束方法( matrixpencilmethod )提取了电路和天线问题的s参数;最后通过分析一些工程中的复杂金属天线问题和具有“金属与介质混合结构”的散射和天线问题验证了方法的准确性和高效性。
