... such a pulse is
IE(r, t)] =
J(x, y)gt[A(z, t)e-i(c~176176
(E.3)
where 9t[q] denotes the real part of q (see, for example, [Agr97]). Here/30 is the value
of the propagation constant fl at the ... description of the actual pulse, we must multiply
A(z,t)
by
exp
(-i (coot - floz))
and take the real part. We will illustrate this in (E.6).
Here we have also assumed that the pulse is o...
