About Course
Electromagnetics Theory is a core course in the Electrical Engineering curriculum. The course covers static and dynamic electric and magnetic fields and their interaction. Major topics include Electromagnetic Waves, Transmission Lines, Waveguides, and Antenna fundamentals. In addition, quasistatic analysis and numerical methods are also discussed.
Electromagnetic covers the basic principles of electromagnetism: experimental basis, electrostatics, magnetic fields of steady currents, motional e.m.f. and electromagnetic induction, Maxwell’s equations, propagation and radiation of electromagnetic waves, electric and magnetic properties of matter, and conservation laws. This is a graduatelevel subject that uses appropriate mathematics but whose emphasis is on physical phenomena and principles.
