NeXT Workstation Laboratory for Undergraduate Electromagnetics

我们建议建立下一个工作站实验室，以补充所有电气工程专业要求的两个学期的初级电磁学课程。最初，实验室是课程的一个可选部分，可能有一些家庭作业需要使用实验室。然而，目标将是最终将实验室整合到课程中，发挥更实质性的作用。为了实现我们的目标，我们已经开始开发一个互动软件包。开发的程序统称为EM笔记本。为了创建Notebook，使用了一种名为数学的强大软件语言。MATHEMICATA具有一项功能，可用于对文本、公式和图形进行分层结构。因此，EM笔记本包含电磁现象的动画序列，例如在波导中传播的波，并且用户可以交互地改变参数，例如频率，随着运动画面的响应而改变。

We propose to create a next workstation laboratory to complement the two-semester, junior level sequence in electromagnetics required to all electrical engineering majors. Initially, the laboratory would be an optional part of the courses, with perhaps a few homework assignments requiring use of the laboratory. However, the goal would be to eventually integrate the laboratory into the coursework in a more substantive role. To accomplish our objective we have already begun developing an interactive software package. The programs developed are collective know as EM Notebooks. To create the Noteboooks, a powerful software language called Mathematica is used. Mathematica has a feature that can be used to hierarchically structure text, equations, and graphics. Thus, the EM Notebooks contain animated sequences of EM phenomena such as waves propagating in a waveguide, and the user can interactively change parameter, such as frequency, with the moving picture altering in response.
