2. 4.5 Uniform Plane Waves in Dielectrics and Conductors

3. Special Cases:
1. Perfect dielectric:
Behavior same as in free space except that 0   and 0  .

4. 2. Imperfect Dielectric:
Behavior essentially like in a perfect dielectric except
for attenuation.

5. 3. Good Conductor:
Behavior much different from that in a dielectric.

6. 4. Perfect Conductor:
No waves can penetrate into a perfect conductor.
No time-varying fields inside a perfect conductor.
