Students in Electrical Engineering have a difficult time visualizing and understanding the abstract and complicated nature of three-dimensional, vector-valued electric and magnetic fields. Thus, the objective of this project is to obtain instrumentation for an undergraduate electromagnetics laboratory that will be integrated into a two-semester electromagnetics course sequence and into senior-level Antennas and Microwave Theory courses. The overall pedagogical goal of this project is to use the equipment to develop a set of experiments that will provide a discovery learning and case study approach to undergraduate electromagnetics-related instruction. Each experiment will be preselected and predefined to illustrate a physical law or concept (i.e. the "case") and the experiments will be outlined in a laboratory manual. The students in these courses will be divided into groups and each group will perform one experiment during the semester. The experiments will also be designed to teach concepts that were not discussed in the class- room so the students have an opportunity to learn and discover material as a team and independently of the instructor. That group will then prepare a lecture to present their findings and the additional concepts to the other students and to demonstrate their experiment. There will be discussions and questions during this session to complete the "case-study" approach The laboratory will allow the students to use dedicated experimental apparatus and state-of-the-art instrumentation to discover and analyze electromagnetic fields and related phenomena and compare with the analytical theory. This provides an excellent opportunity or the students to learn, interact, visualize and completely understand the abstract concepts associated with electromagnetic theory. These experiments re intended for junior and senior Electrical Engineering majors and will affect approximately 1,500 students over the course of 10 years, an estimated lifetime of a majority of the equipment.

电气工程领域的学生很难可视化和理解三维矢量值电场和磁场的抽象和复杂性质。因此，该项目的目的是获得本科电磁实验室的仪器，该实验室将集成到两学期的电磁课程序列中，并纳入高级天线和微波理论课程中。该项目的总体教学目标是使用设备来开发一组实验，这些实验将提供一种发现学习和案例研究方法，以实现与本科电磁相关的教学。每个实验都将被预选和预定义，以说明物理定律或概念（即“案例”），并且将在实验室手册中概述实验。这些课程中的学生将分为小组，每个小组将在学期中进行一个实验。这些实验还将旨在教授课堂室未讨论的概念，因此学生有机会学习和发现作为团队，独立于讲师的材料。然后，该小组将准备一场演讲，以向其他学生提出他们的发现和其他概念，并展示他们的实验。在本届会议期间，将有讨论和问题来完成“案例研究”方法，实验室将允许学生使用专用的实验设备和最先进的仪器来发现和分析电磁场及相关现象，并与分析理论进行比较。这为学习，互动，可视化和完全理解与电磁理论相关的抽象概念提供了绝佳的机会或学生。这些实验是针对初级和高级电气工程专业的专业的，并且将在10年的时间内影响约1,500名学生，这是大多数设备的寿命。
