A Brief History of Finite Element Method and Its Applications to Computational Electromagnetics

Stefano Selleri was born in Bologna, Italy, in 1966. He received the Laurea cum laude degree in electronic engineering from Bologna University, Bologna, in 1991, and the Ph.D. degree from Parma University, Parma, Italy, in 1995. Since 1997, he has been a Researcher with the Information Engineering Department, Parma University, where he became an Associate Professor in 2002, and has been a Full Professor and the Head of the Department since 2013. Since 2012, he has been a Chair of the IEEE Photonics Society Italian Chapter. His research interests include numerical methods for electromagnetic field analysis in conventional and photonic-crystal fibers and waveguides, fiber-based amplifiers, and optical sensing.意大利帕尔马大学信息工程学院的院长

1. Johan Bernoulli in 1696 proposed the problem of the shortest time path connecting two points at different altitudes A and B

这个从高点往低点滚珠子的游戏，玩过的大佬太多！

Indeed, Isaac Newton, Jakob Bernoulli, Gottfried Wilhelm von Leibnitz, Ehrenfried Walter von
Tschirnhaus, and Guillaume de l’Hopital provided their own solution. In particular, Leibnitz exploited a piecewise linear approximation, which was a first step in his development of differential calculus, which he finally published [6], independently and shortly before Newton [7].

2. 看过一篇老学长的paper，说在中科院考了冯康的硕士，又考了第一名可以出国，冯说要学有限元跟我混就可以了！

鬼佬说While practice was going fast, theory lagged. The first proof of convergence of FEs might be traced to Feng Kang [28], but the paper, being in Chinese, was overlooked.

3.  ANSYS (ANalysis SYStems) ported its punchedcard codes to Apple II in 1980, allowing for a first true graphical interface. 1980年代，Ansys还在玩打孔卡片！不过用在苹果二上！

In electromagnetism, Zoltan and Nicholas Cendes (Figure 3) founded Ansoft in 1984, marketing
HFSS (high frequency structure simulator). Ansoft, after a long partnership with Hewlett-Packard, was finally acquired by ANSYS in 2008. HFSS is currently the standard, de facto, in FE analysis for electromagnetic waves.
