摘要：为解决电磁场逆问题分析计算过度依赖计算机资源这一“瓶颈”问题，提出了一种新的快速全局优化算法。该算法首先应用基于紧支集径向基函数(CSRBF)的改进表面响应模型(RSM)重构原优化问题；然后应用改进的粒子群算法(PSO)对重构的优化问题进行快速全局寻优。研究表明，典型数学函数验证以及电磁场逆问题的分析和计算，验证了算法的全局搜索和快速寻优能力。

Abstract: To release the requirement for tremendously heavy computation resources in the study of electromagnetic inverse problems, a fast global optimizer was proposed, based on the combination of the improved response surface mode (RSM) using compactly support radial basis functions (CSRBF) and an improved particle swarm optimization(PSO). Computer simulation results on a mathematical function and a practical engineering design problem were presented to demonstrate the efficiency and robustness of the proposed algorithm.
