Abstract
The results of first-principles calculations of the electronic
structure and the electron-phonon interaction in MgB2 are used
to study theoretically the temperature dependence and
anisotropy of the magnetic-field penetration depth. The effects
of impurity scattering are essential for a proper description
of the experimental results. We compare our results with
experimental data and we argue that the two-band model
describes the data rather well.
