Abstract
The real part of the optical conductivity is calculated by using the Kubo formula approach, and in the framework of the two-bands model. It is shown that a single-gap model is insufficient to describe the optical behavior of superconductor MgB2 film, but the two-gap model with different symmetries is sufficient to explain the experimental results.
