2. Mie & DDSCAT Theory
Both mie and DDSCAT theory are mathematical-physical based theory, calculate for the scattering and absorption of electromagnetic waves.
Mie theory: assumes an homogeneous, isotropic and spheral targets.
DDSCAT: the targets can be arbitrary geometries and complex refractive index.

3. DDSCAT – Input & Output Input file: ddscat.par
Output file: wxxryyori.avg
The mass of output files need to post-processing in IDL make the output clear to the user.

4. Objective
The purpose of this project is implement an IDL GUI to graphical display the output.
The GUI should include:
Plot selected variables by given different parameters.
Interpolate to calculated the value of each given point in the plotted line.
Plot the results using mie theory and show the difference between these two theories.
