Readings

The table below provides the reading assignments for the course. The required readings are taken from the textbook Electromagnetics and Applications by D. H. Staelin. These readings are listed without an abbreviation in the table. The related reading sections for video demonstrations during the course are abbreviated as H/M. The entire contents of H/M can be found in Supplemental Resources > Electromagnetic Fields and Energy.
