“…We consider the multilayer stack as a uniaxial homogeneous medium, which has the optical axis perpendicular to the plane of interface, i.e., the x-y plane. Now, the wavenumbers corresponding to the TE-and TM-polarized waves propagating in the i th layer of the structure can be determined as 49 In these equations, k 0 is the free-space wavenumber,k iz is the wavenumber of the normal components, k ix = k 0 sin θ , and the subscripts t , ⊥ represent the transverse and normal (directions) permittivity values, respectively.…”
