Electromagnetics-based subjects are fundamental in the electrical and electronic engineering curriculum. Electromagnetic theory is highly mathematical, intensive, and it is perceived as too abstract by students, which makes it a challenging subject to learn and to teach. The growth of computational simulation resources offers opportunities to overcome these challenges. Visualization is one effective way. Visualization tools have been created in the past years with the aim of increasing the interest and engagement of students with the subject matter. Such tools are effective methods of learning, as they enhance the student’s understanding of the mathematical and physical concepts behind the theory, as well as the different applications in areas such as antennas, propagation, microwaves, radar, microelectronics, and so forth. This chapter describes four interactive computational MATLAB-based tools for assisting in teaching and learning electromagnetics. The tools are categorized as either tutorial-based problem-solving computational resources or as simulation and visualization interactive tools. The tools cover a range of electromagnetics topics common to undergraduate electronic and electrical engineering programs. These topics include electrostatics, magnetostatics, dynamic fields, transmission lines, antennas, and propagation. The tools aim to improve student engagement, learning outcomes, reduce staff workload, engage on-line students through blended learning, and increase student interest in electromagnetics education.
