ADDA

[Ilya Stanevich]

Hello,

Can I calculate multi-particle scattering with ADDA?

Thank you.

Dear Ilya,

I am not sure exactly what you mean, but generally ADDA should be usable for any finite set of particles (whether they
are connected or not), given enough computational resources.

More details are given in the reply to a similar question:

If that is not enough, please provide more details concerning your question.

Maxim.

Thank you, Maxim. 

I want to calculate optical properties for the layer of aerosol that consists of evenly spaced levitated aluminium disks oriented horizontally. The layer is plane-parallel and 5 km in width. Is it possible to immitate such layer with ADDA?

ADDA is intended for finite scatterers, while you are interested in infinite particulate medium. As I understand, the
width is much larger than both size of the single aluminum particle and the wavelength. And the particles are spaced
randomly (i.e. not on a perfect grid).

Then you have to use some kind of radiative transfer theory. As an input for the latter, you need optical properties of
single oriented aluminum disks - they can be calculated with ADDA. However, I am not an expert in radiative transfer
theories, so I can't provide detailed advice about using them.
