ECEN 3400 - Electromagnetic Fields and Waves


Catalog Data ECEN 3400 (3). Electromagnetic Fields and Waves. Electromagnetic fields are covered at an introductory level, starting with electrostatics and continuing with DC current, magnetostatics, time-varying magnetic fields, waves on transmission lines, Maxwell's equations and the basics of plane waves. The use of fields in inductors, capacitors, resistors, transformers, and energy and power concepts are studied.
