In a region where r = r = 1 and = 0, the retarded
Question:
In a region where μr = ∈r = 1 and σ = 0, the retarded potentials are given by V = x(z − ct) V and A = x (z/c − t)az Wb/m, where c = 1√μ0 ∈0.
(a) Show that ∇ · A = − μ∈ ∂V/∂t.
(b) Find B, H, E, and D.
(c) Show that these results satisfy Maxwell’s equations if J and ρν are zero.
