A uniform plane wave with

in medium 1 ( 1 , 1 ) is incident normally onto a lossless dielectric slab ( 2 , 2 ) of a thickness d backed by a perfectly conducting plane, as shown in below Fig. Find
a) E r (z, t)
b)E 1 (z, t)
c) E 2 (z, t)
d) ( P av ) 1
e) ( P av ) 2
Determine the thickness d that makes Ej(z, t) the same as if the dielectric slab were absent.
