Question
Energy Density in Dielectrics. A plane wave of given frequency propagates in a perfect dielectric: (a) Calculate the time-averaged stored electric energy density and show that it is equal to
the magnetic volume energy density. (b) Suppose now the dielectric is lossy: calculate the time-averaged-stored electric and magnetic energy densities.Are they still the same?
