Surface Plasmons in Thin Metallic Films for Case Antisymmetrical Configuration of Magnetic Field

For the first time it is shown that for thin metallic films thickness of which does not exceed thickness of skin - layer, the problem of description of surface plasma oscillations allows analytical solution under arbitrary ratio of length of electrons free path and thickness of a film. The dependance of frequency of surface plasma oscillations on wave number is carried out. We consider a case of specularity - diffusive boundary value problems.
