Applied Electromagnetics: Early Transmission Lines Approach

    Numerical simulation helps students understand theory

• MATLAB 2.3 shows when connecting wire must be treated as transmission line.  The student can see WHY the T-Line model is required, rather than just accepting some minimum length criteria on faith.
• In MATLAB example 8.4, a movie is created showing the radiation pattern from a dipole antenna as its length changes. 

    Many homework problems draw on the MATLAB examples

    Simulations can point out when ideal theory can be applied to actual situations

• In MATLAB problem 2.18, students are asked to compare the field from a segment of charge to the field from an infinite length line of charge.  The problem is similar to MATLAB example 2.3, so the programming is not difficult.  Students are able to see that theory for an unrealistic infinite line can be put into practice in some situations.

Example Problems

• Students see the detailed steps needed to solve typical problems

Drill Problems

• Simple problems reinforce problem solving concepts
• Students working through the drill problems will have an easier time with the end-of-chapter problems

Practical Applications

• Illustrates practical nature of electromagnetic theory to motivate students
• Applications include loudspeakers, laser printers, microwave ovens and magnetic levitated trains
