Solution
Assuming the magnitudes of both the eld (E & H) contents of incident
wave to be unity, that is, E
i
= 1 and H
i
= 1, thus the incident power = E
i
H
i
= 1.
Let the reection coefcient for E is Γ
E
= E
r
/E
i
, thus E
r
= Γ
E
Also, the reection coefcient for H is Γ
H
=H
r
/H
i
, thus H
r
= Γ
H
The reected power = E
r
H
r
= Γ

Similarly, the transmission coefcient for E is T
E
= E
t
/E
i
, thus E
t
= T
E
And the transmission coefcient for H is T
H
= H
t
/H
i
, thus ...
