Course Description:

This course deals with the simulation method of electromagnetic transients, which is ubiquitous in applications as diverse as power system transients, IC design, and electromagnetic compatibility. This course mainly concentrates on the numerical theories underlying the electromagnetic transient program (EMTP), and also gives an introduction to the state-of-the-art and advanced methods.
