E
z
and E
y
have standing wave distribution above the reecting surface. The
maxima for E
z
occur at the plane and the odd multiples of
λ
z
/4 from the
plane, whereas for E
y
minima occur at the plane and even multiples of
λ
z
/4
from the plane. Figure 2.17 illustrates the E-eld in parallel polarisation.
2.15.2 Perfect Dielectric
Figure 2.18 illustrates a boundary between two media which lies along y axis.
Two incident rays are striking at points A and B. The energy contents of these
rays are partly reected and remain in medium 1. The remaining part passes
through medium 2 through refraction. Since the velocity o ...
