Navigation:  Scatterers > Composite scatterers

Composite scatterers are mixtures of several general scatterers. If a paint, for example, is composed of several types of inclusions in a host, you can compute the absorption and scattering behaviour of each type individually and then import these data in general scattering objects. Then you create an object of type Composite scatterer which simply adds up the individual absorption and scattering probabilities.

The main window of composite scatterers is this:

 

 

It shows the scattering and absorption probabilities K and S of the mixture. The spectral range can be set by the Range command. It may be different from the ranges of the individual scatterers.

Composite scatterers use a list to manage the general scatterers that make up the composition. The list is opened pressing the List button:

 

 

First, with the button labeled '+' you create as many scattering types as you want to mix. Then you fill each entry with the wanted general scatterer by a drag&drop operation  from the list of scatterers. This list is viewed by pressing the Scatterer button in the main window of SPRAY.
