摘　　要：研究了64位计算技术求解电大尺寸电磁计算问题的能力。基于矩量法(MOM)的基本原理,利用C语言开发32位矩量法计算程序,给出算例验证程序的有效性。分析32位系统对程序的限制发现,对于电大尺寸问题,当内存需求大于2.2 GB时,32位程序无法计算。利用64位编程技术,开发了64位矩量法的计算程序。对比表明,64位技术能明显提高矩量法的计算范围,增强了矩量法求解电大尺寸电磁计算问题的能力。64位计算技术,提供了矩量法求解电大尺寸目标的另一种途径。Electromagnetic computation of electrically large objects by using 64-bit computing technique is studied.The method of moments（MOM） program is developed in 32-bit system.Numerical results are presented to validate the accuracy of the program.The limitation of the 32-bit MOM program is discussed and it is found that the 32-bit MOM program can not work when the demand on memory is over 2.2 Gigabyte.The 64-bit computing technique is studied and the corresponding 64-bit MOM program is developed to extend the capability of the current MOM program.Numerical results and comparisons are given,which indicate that the 64-bit computing technique can extend the capability of MOM obviously for solving electrically large electromagnetic computation problems.
