Abstract:
Operational and Wantzel-Kramers-Brillouin (WKB) methods are utilized
to obtain an analytical approximate
solution of the Beechem-Haas equation for the initial/final-value problem
with system parameters of radial profile. The Beechem-Haas equation herein
is expanded from its traditional form, which determines its solutions in a
spherical coordinate system as functions of the radial and time coordinates
only, to one which includes the angular coordinates as well, thus providing
a natural modeling framework for polarization phenomena.
