Hi Peng! plz keep in mind that :

metals whose optical prop are studied should be necessary applied to waveguides only.

Wien2k I am using could also do such kind of cal. Shall I help?

Alan F Rawle

Which metal(s)? What wavelength? The optical properties for virtually all the metals have been measured over a wide range of wavelengths. No need to calculate if they've actually been measured...

Hi Prof. Merabet:

Thank you for your kind help! Sorry you did not hear from me for quite some time as I am in the middle of a big move from Shanghai to Beijing. Could you provide me some example of Wien2K calculations on metal? Thank you very much!

Best regards,

Dear Prof. Rawle:

Metallic hydrogen actually. So I wonder if GW+BSE could help. If not, may I use the experimental values for intraband transition?

Hi Peng again! We performed cal on NiSi and results are so exciting; ready to help!

Hi Prof. Merabet! Thank you for offering kind help! Could you provide me any example of Wien2K calculations on optical properties of metal, especially for intraband transition? My e-mail address is [[email protected]]. Thank you very much ;)
