Vacuum fields?

How can we calculate the vacuum fields corresponding to certain frequencies?

From some reference I got following information.


Vacuum fields are noises in a system. And the by some calculations, we get roughly
1nW of power for different frequencies. Although, it is really small but very useful in some cases.

May be it helps some one looking for similar solution.
