MIETAB is a Mie scattering program for Microsoft Windows 3.x.

MIETAB can calculate the Mie efficiency factors and phase functions
for homogeneous spheres in the size parameter range 0.01 to 400 at
up to 181 angles. It allows looping over up to 101 sizes in a single
computational "run". Only one wavelength can be treated within a
"run". The program displays numerical data for the efficiency factors
in its main window and can display simple graphs of phase function vs
scattering angle and (with looping) efficiency factors vs size. Numerical
results and graphs may be transferred to the default Windows printer if
it can print such things. Users must supply all optical data, etc via
data input dialogs.

MIETAB requires an 80286 or higher computer running Windows 3.0 or
later and which has an 80x87 or equivalent math coprocessor.

The Mie scattering routine used in Mietab is based on the continued
fraction method of W. J. Lentz (See W.J. Lentz," Generating Bessel
functions in Mie scattering calculations using continued fractions",
Applied Optics, Volume 15, Number3, March 1976), and had its origins in
Lentz's modification of a FORTRAN program originally devised by J. V.
Dave. Lentz's original FORTRAN code has been extended to handle all
four of the Van de Hulst "i" functions and the "radar" efficiency factor
(the latter was mainly done by Edward Burlbaw). A. Miller, the MieTab
developer, converted the FORTRAN code to Turbo Pascal ( a translation
which required that all complex arithmetic be done "by hand" and
reprogrammed to use only real numbers) and was responsible for all
programming associated with MieTab's Windows capabilities. (The actual
Mie calculation routine comprises fewer than 400 of the 5600 lines
of MieTab's source code.)

The Windows interface incorporated into MieTab was written in Borland
International's Turbo Pascal for Windows. Aside from some internal routines
based on exampled found in the Borland manuals, the Windows interface used
in MieTab is solely the work of the undersigned author.

MIETABxx.EXE itself is a proprietary shareware product and a registration
fee of $ 55 is applicable after a free evaluation period of one month. This
fee is for use of the Windows interface, not for use of the Lentz algorithms.
