在电磁学中，优化问题通常需要大量的计算资源，并涉及大量的未知数。它们通常以非凸泛函和连续空间为特征，适用于基于差分进化（DE）的策略。在这样一个框架中，本文的目的是在电磁学中使用的差分进化为基础的方法的概述，指出其他领域的应用的新颖性和定制。从差分进化的进化机理出发，提出了基于差分进化的电磁优化技术。文中还给出了算法的收敛性和对控制参数的敏感性。最后，不同的差分进化公式在计算电磁学领域解决优化问题的全面覆盖，侧重于天线合成和逆散射。
In electromagnetics, optimization problems generally require high computational resources and involve a large number of unknowns. They are usually characterized by non-convex functionals and continuous spaces suitable for strategies based on Differential Evolution (DE). In such a framework, this paper is aimed at presenting an overview of Differential Evolution-based approaches used in electromagnetics, pointing out novelties and customizations with respect to other fields of application. Starting from a general description of the evolutionary mechanism of Differential Evolution, Differential Evolution-based techniques for electromagnetic optimization are presented. Some hints on the convergence properties and the sensitivity to control parameters are also given. Finally, a comprehensive coverage of different Differential Evolution formulations in solving optimization problems in the area of computational electromagnetics is presented, focusing on antenna synthesis and inverse scattering.
