Question:
Consider time-harmonic electromagnetic fields in the domain z ≥ 0 of the form
(a) Let ŷ · ETE(x, z = 0, t = 0) = E̅y (x). Determine the scalar function ΛTE(kx) and the vector function TE(kx) so that
solve Maxwell’s equations in free space. The wave vector k = x̂ kx + ẑ kz is two-dimensional. Explain why there is no integral over kz.
(b) Let x̂ · ETM(x, z = 0, t = 0) = E̅x (x). Determine the scalar function ΛTM(kx) and t
he vector function "ΓTM(kx) so that
solve Maxwell’s equations in free space. The factor k0 = ω/c.
(c) Represent a general z ≥ 0 field as E = ETE + ETM and B = BTE + BTM. If S is the Poynting vector, show that the time-averaged power transmitted down the z-axis is
What is the physical origin of the limits of integration on the kx integral?
