Translight metal

Hi All,

I try to get transmission coefficients of metallic structure using Translight, but whenever I set metallic features, it gives error in the meantime of calculation.

I would be grateful, if anyone experienced with Translight could help me. Please explain the steps how to set metal.

Thanks in advance,

I am doing my Thesis in Analysis and design of metallodielectric photonic crystal filter ,I have to get R and T(reflection and transmition of fields) of the filter that i have to design in IR Visible and UV range , so how femlab can help me and how can i run it for using in design filter,i studied its help and became familiar with it somehow but i need to know more how to use it,for example how to design and give information for running it to get answer.
plz if you can ,guide me.
