At this stage, the reflection and transmission coefficients of the TE/TM‐polarized waves at the interface of two physical media could be computed. Using the above discussion, the reflection coefficient and the transmission coefficient of an obliquely incident TE (perpendicular) – polarized wave are computed from the transmission line model as follows:

(5.2.27)

Equation (5.2.27a,b) are identical to equation (5.2.8c,d), The reflection coefficient and the transmission coefficient of an obliquely incident TM‐polarized wave are further computed using the transmission line model, shown in Fig (5.3b), as follows:

(5.2.28)

Equations (5.2.23) and (5.2.26) are used to get the above expressions. Equation (5.2.28a, b) are identical to equation (5.2.16c,d). The transmission line models are also used to obtain the reflection and transmission coefficients of both normal and oblique incident plane waves on a multilayered slab medium [B.1, B.3, B.4]
