Question - Electromagnetic waves propagate much differently in conductors than they do in dielectrics or in
vacuum. If the resistivity of the conductor is sufficiently low (that is, if it is a sufficiently good
conductor), the oscillating electric field of the wave gives rise to an oscillating conduction current that
is much larger than the disp1acement current. In this case, the wave equation for an electric field E(x,
t) = E,(x, t)J propagating in the +x-direction within a conductor is where µ is the permeability of the
conductor and p is its resistivity.
(a) A solution to this wave equation is where kc = vwµ/2p. Verify this by substituting E, (x, t) into the
above wave equation.
(b) The exponential term shows that the electric field ...Read More
