Abstract Local expectation values of the electromagnetic energy density, and of the quantity 1 4 G 2 = 1 2 ( H · B − E · D ), are calculated both inside and outside a spherical surface dividing two media of permeabilities μ 1 and μ 2 . In both media the relationship eμ = 1 is assumed, where e is the permittivity. The powerful source theory method is used. The results are displayed graphically, although analytical approximate expressions for the field densities are obtained near the surface. The… CONTINUE READING
