where k0=2Tc/2. and
k21[ko2 k12]'2 (3)
where A. is the light wavelength and k0 is the amplitude of wave vector in vacuum, k2 and k1 =
k0 n1 sini are wave vector components in media along the z and x directions respectively,
here ji is the angle of incidence.
By applying the boundary conditions at z=z1 interface, the relation between the parameters
in the layers ofj and j+1 can be obtained
