中文摘要:
      用一种高效的矩阵填充技术快速计算含周期结构复合模型的阻抗元素。通过分析传统聚合基函数,提出了一种能在复合结构区域划分基础上,结合等效偶极矩技术快速生成基函数的办法。减少阻抗矩阵方程的填充时间,并实现对模型所包含周期性质的充分利用,简化了传统计算方法对目标的复杂剖分过程。仿真结果表明,该方法大大提高了计算速度,降低了计算机内存需求。
英文摘要:
      This paper applies an efficient impedance filling technique to calculate the impedance elements of composite model with periodic structure. After analyzing the method of dividing the composite structure by the traditional aggregate basis function, we combine the equivalent dipole moment technique to quickly generate the basis function and reduce the filling time of the impedance matrix equation. This method makes full use of the periodic nature of the model, and simplifies the complex division process. The numerical calculation result shows that this new method can improve the computing speed and reduces the computer memory cost.
