APPLICATIONS
Personal wireless services • cordless telephony • cellular telephony → PCS • mobile data transfer • personal satellite communications • global navigation systems
Knowledge of electromagnetics is required to explain certain technologies: – antennas
• transmitter and receiver are connected by a “field.”
Why is Electromagnetics Important?
• Electromagnetism is a fundamental branch of physics dealing with all aspects of the generation, propagation and transformation of electromagnetic energy as well as its interaction with matter.

What do we study
• E.M. studies stationary charges, moving charges, the fields produced by them, and the interaction with matter.
• The field is a special substance, we must study its energy, mass, momentum, and motion behaviors.
