- TL;DR Summary
- Emitted blackbody radiation into a medium with complex refractive index

Hi.

If the refractive index of a medium equals one, the total emitted blackbody intensity inside a medium is sigma*T^4.

In general, if the refractive index of a is a real number, the total emitted blackbody intensity inside a medium is n^2*sigma*T^4.

Now, when the refractive index of the medium is complex (n + ik), what will be the expression of the total emitted blackbody intensity inside the medium?

Will it be n^2*sigma*T^4 as before, or maybe (n^2+k^2)*sigma*T^4?

Thanks.
