Engineering 6813 — Electromagnetic Fields Fall, 2002
Instructor: Eric Gill Office Number: EN3046 Phone: 737-8922 Email: egill@engr.mun.ca
This is the second of two elementary courses, the first being Engineering 5812, designed to prepare students for further applications in engineering electromagnetics. Briefly reviewing the concepts associated with steady electric and magnetic fields, the material proceeds logically to the problem of time-varying electromagnetic fields. The ideas encountered will be essential to the understanding of applications in, for example, antenna theory and design and will provide the physical foundation for the discussion and derivation of the governing equations for various communication channels (eg. transmission lines, optic fibres, waveguides, etc.).
