Grasp the theory and
you're almost there
Material to be considered in this section includes dielectrics, loss
mechanisms, power deposited, and interaction of microwaves with dielectrics
and metals. The nature of fields in cavities that contain some dielectric
load will be examined as well as differences between single and multimode
resonant systems.
1. Wave propagation in space
2. Wave propagation in materials
3. Loss mechanisms
4. Waveguides
5. Resonant cavities

Electromagnetic
Waves
exist in nature in the radiation that takes
place when atoms or molecules change from one energy state to
a lower one, with frequencies from microwave through visible into
x-ray regions of the spectrum. These natural radiation's are utilized
in astronomy and radio astronomy. Telecommunication, navigational
guidance, radar and power transmission depend on our ability to
generate, guide, store, receive, radiate and detect such waves.
This involves many types of structures whose properties the designer
must predict. The complete set of laws for time varying electromagnetic
phenomena is known as Maxwell's equations and are central
to such predictions. (Ramo,Whinnery and Van Duzer)
