Figure 12.10 (a) Plots of p [Eq. (69)] as functions of
the incident angle, θ 1 ,as shown in Figure 12.7a. Curves are
shown for selected values of the refractive index ratio,
n 1 /n 2 . Both media are lossless and have µ r = 1. Thus
η 1 = η 0 /n 1 and η 2 = η 0 /n 2 .(b) Plots of s [Eq. (71)]
as functions of the incident angle, θ 1 ,as shown in
Figure 12.7b.Asin Figure 12.10a, the media are lossless,
and curves are shown for selected n 1 /n 2 .
