The polarization, et, of the positive going field is determined by ~ . Ei = 0 and ~""!"
(equation (4.8)) as
(0.·1)
and therefore
E+ = e-+E:'-
1 1 1·
(D.5)
Thus. equation (D.3) can be written as
-E+ H+
niY i = i·
(0.6)
Csing equations (4.9) and (D.4) we can express the positive going electric field in
terms of the positive going tangential electric field as
(0.7)
Combining equations (0.6) and (D.7) leads to
(0.8)
with
(0.9)
A derivation for the negative going waves leads to an equation similar to equation
(0.8), and thus to equation (4.15).
