“…The fact that teaching Electromagnetics is difficult is not personal or local problem, rather it is universal. In a good survey to see how is teaching Electromagnetics around 13 countries in the world [1], the answer is surprising. There appears to be a nearly universal decline in students' interest in Electromagnetics.…”

The paper presents a novel qualitative approach for the analysis of rectangular waveguides. The approach is based on understanding the nature and the behavior of the wave propagation outside and inside the waveguide, and the boundary conditions of the electric and magnetic fields on the waveguide walls. The six field components for TE or TM modes are concluded as well as the other properties of the wave. However, the approach is incomplete since the wave impedance in the guide is the only parameter which is undefined yet. The new approach is simple, versatile, and gives the reader good insight. It is very useful when used to emphasize the analysis to undergraduates. This analysis is limited to waveguides which are uniform longitudinally. However, the approach will be elaborated to handle waveguide discontinuities, junctions, rectangular cavities and other EM structures in the near future. The main advantage of the proposed approach is that it avoids the usual difficult solution of the wave equation by the method of variables although the results obtained with the proposed approach are the same. The results of the surveys on how the proposed approach improved the teaching/learning outcomes are discussed.

Use the analytic formulae (1) and (2) to check the accuracy of the numeric calculations. For the numeric calculation of inductance, values for the coil currents must be specified and, in magnetically linear problems, the values for electric currents may be chosen arbitrarily [16].…”

“…The literature documents extensive research into the development of computer-assisted educational material to teach physics and engineering. Fortunately, there are excellent surveys intended to aid faculty members in their choices related to curriculum changes and incorporation of innovative educational methods [2] [3]. There are many papers describing new approaches to teach electromagnetics and, almost without exception, these papers advocate the integration of field computation into electromagnetics teaching.…”

The paper describes an approach to teaching mutually-coupled circuits CAD techniques to undergraduate students pursuing a degree course in electrical engineering or physics, and explains how a series of simulated experiments may be incorporated into the existing subjects. The simulated experiments make use of a two-dimensional open-access software based on the finite-element method. At the laboratory meetings, the students learn how to set up field problems for solution, and how to examine the results. Simulation tasks based on three axisymmetric open-boundary problems are used to introduce different numeric techniques to compute inductance and magnetic forces. The paper takes the reader to a step-by-step simulation journey, and provides all the basic elements required for further exploration of axially-symmetric systems.

“…However, the teaching of the basic area of electromagnetics has been considered, for sometime, to be a challenge and a matter of concern due to low student motivation [3], poor attendance, and student underperformance in electromagnetic courses [4]. This was attributed to the mathematical complexity and abstract nature of the topic [5].…”
