In innocence, we see the beginning. In passion, we see the end. Lao Tse (605-531 BC) Objectives • To provide the basic theory pertaining to microwaves and other high-frequency devices and subsystems • To examine some of its applications to modern communication systems Motivations • Practical Reasons: – Useful – Fundamental – Increasing important • Energy/power generation & transmission • Telecommunications • Other emerging applications • Intellectual Reasons – Rigorous – Elegant – Challenging • Laws of EM waves have certain beauty about them that can be appreciated by those who understand them on an aesthetic level.
