CHAPTER 3
3.1. An empty metal paint can is placed on a marble table, the lid is removed, and both parts are
discharged (honorably) by touching them to ground. An insulating nylon thread is glued to
the center of the lid, and a penny, a nickel, and a dime

The Chronology of Electromagnetics
~900 BC: Certain rocks (later called magnetite) were found to attract iron bits and bits of
straw.
~600 BC: Greek philosopher Thales described how amber, after being rubbed with cat fur,
could pick up feathers (static el

Uniform Plane Waves
2. Uniform Plane Waves
Because also z Ez = 0, it follows that Ez must be a constant, independent of z, t.
Excluding static solutions, we may take this constant to be zero. Similarly, we have
Hz = 0. Thus, the elds have components
