An x polarized uniform plane wave travelling in z direction undergoes reflection thus the electric field of the standing wave is represented as Ex = Ae*jkz + Ce+jkz¸ The phase velocity of the wave is given by: %3D (A) vp = 1/veµ (A -C)/(A +C) cos2kz (B) vp = 1/veµ [(A -C)/(A +C) cos2kz + (A+C)/(A-C)sin2kz)] (C) vp =1/Veµ (A -C)/(A +C) sin2kz (D) vp = 1/Veµ (A -C)/(A +C) tan2kz.
