 → Course Description
Electromagnetics is the study of the effects of electric charges at rest and in motion. It is indispensable in understanding the physical principles of electric circuits, microwave devices, wireless communication, optical-fiber communication, electrical-noise occurrence, electromechanical energy conversion such as electric motors and generators, and so on. Positive and negative charges are sources of an electrical field.  Moving charges produce a current, which gives rise to a magnetic field. Time-varying electric field and magnetic fields are coupled, resulting in an electromagnetic field.  Under certain conditions, electromagnetic fields produce waves that radiate from the source. Electromagnetics can be developed axiomatically starting with the set of four Maxwell's equations as fundamental postulates. Introductory electromagnetic is covered through a two-semester sequence of two courses, Electromagnetic Theory I and II. Particularly, in this course, Electromagnetic Theory II, the materials studied in the first course, Electromagnetic Theory I are generalized from static cases to time-varying cases. Students also learn the operational principles of transmission lines, wave guides , cavity resonators, and antennas used for effective guide and radiation of electromagnetic waves.
