A uniform plane wave with

in medium 1 (∈1, μ1) is incident normally onto a lossless dielectric slab (∈2, μ2) of a thickness d backed by a perfectly conducting plane, as shown in below Fig. Find

a) Er(z, t)

d) (Pav)1

---

e) (Pav)2

Determine the thickness d that makes Ej(z, t) the same as if the dielectric slab were absent.
