A uniform plane wave travelling from air into non-magnetic medium with permittivity ϵ = 2ϵ0. The wave travelling in x-z plane, under goes oblique incidence at the boundary z=0 of two media at an angle of 45°. If the polarization is parallel, then the unit vector along the direction of transmitted wave E̅ field is
1
\(\frac{{\sqrt 3 {a_x} - {a_z}}}{2}\)
2
\(\frac{{{a_x} - \sqrt 3 {a_z}}}{2}\)
3
\(\frac{{{a_x} - {a_z}}}{{\sqrt 2 }}\)
4
\(\frac{{{a_x} + {a_z}}}{{\sqrt 2 }}\)
