Transverse electrical conductivity and dielectric constant of a polycrystalline metal

The behavior of a degenerate electron plasma under the action of an alternating transverse electric field of weak intensity is considered. The linearized kinetic equation for electrons in a polycrystalline metal is considered. This kinetic equation takes into account the scattering of electrons at the boundaries of crystallites of a polycrystalline metal. On the basis of this equation, an expression is obtained for the transverse conductivity and transverse dielectric constant of a polycrystalline metal.
