# ELEX 7230 - Electromagnetism

## Electrical and Computer Engineering Part-time Studies Course

### School of Energy

BCIT is planning for a substantial return to on-campus activity for the fall 2021 term as informed by BC Public Health Officer guidelines. Refer to each course listing for details.

# Course Details

This course covers the theory of electromagnetism, including field concepts, Maxwell's equations free space and guided wave propagation, transmission lines and radiation from simple structures. Application examples in high-speed circuit board design, ionosphere modeling, and antenna theory are included. Computer simulations are used to help students visualize the concepts presented in the course.
