### ECE 3106 Electromagnetic Fields (3C)

Maxwell's equations and their application to engineering problems. 3105: Electrostatics, steady electric currents, magnetostatics (through Materials). 3106: Magnetostatics (inductances, forces, energy), time-varying fields, waves and propagation, transmission lines, waveguides.

What is the reason for 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, as well as electrical, optical, and photonic devices. This course provides instruction in the fundamental engineering science and also the basics of modern applications.

*Required for all EE majors; Technical elective for CPE majors*. Typically offered: Fall, Spring, Summer II. Program Area: Electromagnetics.

*Prerequisites: C- or better in 3105*.

Why are these prerequisites or corequisites required?

Proficiency in differential equations, vector calculus, electricity and magnetism, phasors, and basic circuit concepts is necessary. Consequently, students must have 2004, Math 2216, and Physics 2306 as prerequisites.
