| 摘 要： | 为分析安装于诸如飞机、舰艇等复杂目标上多天线的电磁兼容性,本文引入了Costa基函数对多天线线面连接结构进行建模.针对计算量过大、耗时太长这一主要障碍,结合RWG基函数特点,设计了一种高效的适用于共轭梯度方法求解的棋盘状并行矩阵填充算法,避免了RWG基相互作用的重复计算,然后详细地讨论了并行共轭梯度算法求解矩量法矩阵方程的并行实现过程.本文进一步开发并在PC集群中实测了MPI并行矩量法程序性能,作为应用计算了安装于某飞机头部的多天线辐射特性.

| Abstract: | An efficient method of moment with Costa's basis function is introduced to analyze the EMC of multiple antennas mounted on complex shaped conductors.Too much time and prohibitive computation resources are needed for the EMC analysis of complicated EM environment.To overcome this drawback,a parallel algorithm that combines MoM with MPI functions is studied.The tessellation scheme is employed for parallel filling the impedance matrix and Parallel Conjugate Gradient method is used to solve the matrix equation.Several numerical results are presented to demonstrate its accuracy and efficiency. |
