The Reason this Course is in the Program:

High frequency/high speed/ wireless communications, based on time-varying electromagnetic fields belong to the most important areas of electrical/electronics/computer engineering. Our students need a good theoretical background for design and applications in those areas. This class is designed to provide the students with that background, together with a basis for further study.
