A slab of perfect dielectric material (epsi _(r)=2) is placed in a microwave oven. The oven
produces an electric field (as well as a magnetic field). Assume that the electric field intensity is
uniform in the slab and sinusoidal in form and that it is perpendicular to the surface of the slab.
The microwave oven operates at a frequency of 2.45GHz and produces an electric field intensity with
amplitude 500(V)/(m) inside the dielectric:
(a) Calculate the displacement current density in the dielectric.
(b) Is there a displacement current in air? If so, calculate it.
