Calculation of the electromagnetic absorption by a small metal particle with a two-parameter kinetic equation

The behavior of the magnetic dipole absorption cross section in a small metal particle is considered. A modified kinetic equation with the collision integral taking into account the deviation of the properties of metals at low temperatures from the Wiedemann-Franz law is solved. Diffuse reflection of electrons from the sample surface is considered. The dependence of the absorption cross section of a particle on the parameter describing the deviation from the Wiedemann-Franz law is analyzed.
