Introduction 22

Wireless communications systems require antennas To better understand modern communications and

computer systems. To be able to design and analyze electromagnetics-

based devices

Why Electromagnetics is difficult?Why Electromagnetics is difficult?

Introduction 23

Because Electric and Magnetic Fields are three-dimensional are vectors vary in space as well as time are governed by PDEs

As a result Solution of electromagnetics problems requires a high level of abstract

thinking – which is an ability to think three dimensionally in space.It is not possible to solve them by finding the right formula in which to plug the numbers.

Students must develop a deep physical understanding of wave propagation mechanisms where math becomes a powerful tool rather than a crutch
