In a perfect dielectric medium (σ=0) having permittivity image from custom entry tool and permeability image from custom entry tool, an antenna array consists of two infinite plane parallel sheets in the x-y plane spaced half a wavelength apart, and having respective surface current densities

Js1 = -Js0 cos (ωt)i^ ; z=0

Js2 = Js0 sin (ωt)i^ ; z=λ/2

Find the electric field density and the magnetic field energy density everywhere.
