Abstract:Undergraduate electromagnetic field courses entail significant teaching and learning challenges. The use of simulation technologies in these courses can be an effective teaching strategy if designed properly. An assessment-based approach for identifying difficult concepts to incorporate into simulation-oriented learning is investigated. The potential benefits of the approach are illustrated with a case study.
“…The ever increasing availability of simulation tools and physical experiments are certainly promising and, based on information from those implementing them, appear to be effective. Effective in both generating student interest and removing some of the abstractness associated with the topic [5], [6]. However prohibitive cost of equipment from commercial sources, i.e.…”
This writing describes a 5.8 GHz microwave system that is suitable for use in undergraduate laboratories or as a demonstration tool. The system is constructed mainly from off-the-shelf components and can be configured by anyone possessing a basic knowledge of electronics. The types of demonstrations that the system can be used for is vast and cannot be addressed in a single writing. Therefore, the authors outline one exercise and results that explores wave interference based on propagation and phase delays. The phase delays are produced via spatial and feed line delays.

“…To help those students who may not have a sound knowledge of vector calculus, the visualization tool and demonstration are important. There are extensive reports on computing and visualization the EM concepts from past published papers [5][6][7][8][9][10] . In this paper, the basic software used for computing and demonstrating the EM fields are Matlab 11,12 and Mathematica 13 which provide features of vector operation and graphical demonstration.…”
Electromagnetics(EM) is a traditionally difficult subject for engineering students. The understanding of the field concepts requires a lot of advanced mathematical knowledge and analytical ability. This course is particularly important for understanding a lot of electrical phenomena.The objective of this paper is to develop computer assisted materials to generate plots and animations for EM fields. Extensive examples are shown to help illustrate the concepts of static electric field and steady magnetic field, dynamic fields and radiation.
“…Electromagnetic (EM) theory education suffers from a lack of student interest and learning challenges due to extensive mathematical concepts, operations with geometry and the abstraction of concepts [1,2]. Different approaches have been proposed to address the challenges, such as hands-on-experimentation [2], the inclusion of computer aided design tools [3] and, more recently, augmented reality (AR) techniques [4]. Recent rise in popularity of 3D-enabled screens and highly improved capabilities of graphical processing units (GPUs), it is now possible to generate complex and real-time 3D visualizations that facilitate teaching of broad scientific topics [5].…”
Florida. He was an Instructor in the topics of Optical Communications and Guided Waves Systems Laboratory at his Alma Mater until the end of 2014, when he joined the University of South Florida. He is currently pursuing his Ph.D. degree conducting research within the group of Dr. Gokhan Mumcu. His research focus is on the realization of RF reconfigurable devices by using microfluidic technology, specifically filters, RF switches, antenna elements and antenna arrays. He has also developed around fifteen 3D visualizations for enhancing and complementing the teaching of electromagnetic theory in undergraduate courses. The visualizations cover topics of Vector Algebra, Vector Calculus and Electromagnetic Field Theory, Electrostatics and Time-Varying Fields through different interactive animations that can be displayed on 3D-enabled screens.
