Hi again,
It is quite hard to know absorption coeffs. for metal, plastic, paper, and 
plant without knowing the thickness of the material (and on top of which 
material they are mounted). However, I just made an educated guess for 
coeffs. ann you can find coeffs here. I don't have a clue, how to add 
materials in the system, could, e.g., Emil do that, please?
