Abstract: This paper provides an overview of the research progress in computational electromagnetics and electromagnetic industry software. First, it introduces the advancements in computational electromagnetic methods, covering analytical methods, high-frequency approximation methods, full-wave computation methods, and fast computation methods, as well as hybrid methods that have developed in recent years. Second, the overview summarizes the characteristics and development history of three major types of international commercial electromagnetic computation software based on full-wave computation methods such as the Finite-Difference Time-Domain (FDTD) method, Finite Element Method (FEM), and Method of Moments (MoM). Third, the algorithm system, software functionality, and practical applications of Yaoguang, a high-frequency electromagnetic industrial software with independent intellectual property rights in China is introduced. Finally, we conclude with a summary and outlook on the future development of computational electromagnetics and electromagnetic industrial software.
