Plane Wave Propagation through a Good Conductor and Total Internal Reflection

Plane Wave Propagation through a Good Conductor

When an EM wave is propagating through a conducting medium, the amplitude of E and H Vectors and hence the EM energy goes on decreasing and finally the wave is absorbed in the conducting medium. Conduction current term dominates the displacement current term in the wave equation for E. the wave equation reduces to the one as

Skin depth is defined as the distance after travelling which the amplitude of the electric field vector reduces to 1/e times the original amplitude. The loss of…
