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. 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.
Using 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, 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). The developer of MieTab converted the FORTRAN code to
Pascal, a translation which required that all complex arithmetic be done
"by hand" and reprogrammed to use only real numbers.

Copies of the FORTRAN code are belived to be in the public domain and will
be sent to any US citizen upon receipt of an MS-DOS formatted diskette and
a self addressed diskette mailing container carrying uncancelled postage
stamps in an amount adequate for its return. The MIETAB developer offers no
warranty whatsoever as its utility, validity or as to its freedom from third
party claims. Nor is there any offer of assistance in making use of the
FORTRAN 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 interface, not for use of the original FORTRAN code.

MIETABxx.ZIP is may be freely distributed in its original archive form, but
may not be distributed in any fashion for profit without written consent
of its developer.

No warranty of any sort is supplied with MIETAB (period!). You test it or
use it entirely at your own risk.
