Greetings,

Could anyone help to tell me how to estimate the dielectric constant of cobalt oxide?
Cause I have looked for the database, and couldn't find the data.

Very thanks,
jovis

As a first approximation, you could use the http://en.wikipedia.org/wiki/Clausius%E2%80%93Mossotti_relation" [Broken]. The best approach typically though is to use experimentally measured values found in handbooks such as the CRC handbook.

Hi chrisbaird,

Thanks a lot for your reply. I just checked the CRC handbook for the dielectric constants of cobalt oxide. But it seems to me it has only a very rough value, 12.9 within the frequency between 10^2-10^10.

http://books.google.com/books?id=q2...&resnum=2&ved=0CCEQ6AEwAQ#v=onepage&q&f=false

I wonder if there is data of complex dielectric constant verse wavelength or frequency.

Thanks a lot,
jovis

You will probably need to find a paper in a scientific journal for such comprehensive information.

You may not like this answer, but: If you need high-accuracy, high-resolution dielectric constant values over many frequencies, and you cannot find it in the scientific literature, you may need to hire a laboratory to take the measurements for you.
