<DIV>Dear WIEN users,</DIV>
<DIV> </DIV>
<DIV>I am calculating optical properties for a spin-polarised system. I have *.epsilonup and *.epsilondn. </DIV>
<DIV> </DIV>
<DIV>How can I obtain the optical properties, such as reflectivity? Should I calcuate them separately i.e (for majority -spin and minority spin) ? If not how can I do it please.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
