Course Information


ECE 3106: electrostatics and magnetostatics, Maxwell's Equations, wave propagation in uniform media, the reflection and transmission of plane waves, guided waves, radiation

Why take this course?

Electromagnetics provides the mathematical description of all electrical phenomena, and therefore it is the physical foundation of all Electrical and Computer Engineering disciplines. Modern applications of electromagnetics are broad and include wireless communication systems, global navigation systems, bioelectrical phenomena, high speed computers and computer networks, and electromagnetic phenomena in Earth's near-space environment (space weather) as well as electrical, optical, and photonic devices. This course provides instruction in the fundamental engineering science and also the basics of modern applications.

Learning Objectives

  • Apply Maxwell's equations to calculate the electrostatic and magnetostatic fields produced by distributed charges and currents
  • Apply Maxwell's equations to analyze the propagation of waves in conducting and dielectric media
  • Analyze the transmission and reflection of plane waves at the boundary between two materials
  • Analyze propagation in waveguides and the radiation produced by a Hertzian dipole
