# ELECTROMAGNETIC ENGINEERING II

## TEXT:

Fields and Waves in Communication Electronics, Third Edition, by Simon Ramo, John R. Whinnery and Theodore Van Duzer (John Wiley & Sons, 1994). Dr. Ramo is the "R" in TRW, Inc.

## TARGET AUDIENCES:

• This is an elective course for Junior or Senior undergraduate students in Electrical Engineering.
• EE4301, Electromagnetic Engineering I, is a recommended prerequisite. Students who have not yet taken EE4301 should discuss their readiness for EE4302 with Dr. Cantrell before signing up.
• An understanding of the material in this course is recommended for all students who intend to work in wireless or fiberoptic communications engineering.
• Others who can benefit from this course include employees of local high-technology companies who need an overview of the principles of waveguides, resonators, and transmission lines.
