| 摘要: |
| 基于电磁场时域积分方程(TDIE)数值技术计算复杂目标的瞬态散射特性，其计算量和内存需求大，采用时域自适应算法(TDAIM)降低了TDIE的计算规模。在研究TDAIM并行算法的基础上，开发了基于.NET Remoting的电磁场分布式数值计算方案。数值结果表明，该方案显著提高了TDAIM的计算效率，为解决电大目标瞬态电磁散射问题提供了一条有效途径。 |

| Abstract: |
| The high computational complexity and large memory requirements will be encountered when the transient responses from electrically large complex objects are considered using time domain integral equation (TDIE) numerical technique. Time domain adaptive integral method (TDAIM) is employed for reducing the computational scale of TDIE. The parallel technology was researched and the distributed electromagnetic computation based on .NET Remoting was implemented. Results show that the parallel scheme is effective for improving computational efficiency and solving the large scale electromagnetic problem. |
