Wave Propagation in lossy media
Dielectrics differ from conductors in that they have few (if any) free charges available for conduction.
They do, however, have fixed, or bound, charges that influence the field within the material. Imagine
the electron clo

As a TEM wave enters a lossy medium, the loss mechanisms (conduction loss and polarization loss)
cause the wave to attenuate due to the energy loss. We can refer to the rate of the attenuation in
different ways, much
