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

TL;DR

This paper provides an analytical solution for surface plasma oscillations in thin metallic films, considering various electron mean free paths and boundary conditions, and explores their frequency dependence on wave number.

Contribution

It introduces an analytical approach to surface plasma oscillations in thin films with arbitrary electron mean free path ratios and boundary conditions.

Findings

Analytical expressions for surface plasma oscillations are derived.

Frequency dependence on wave number is characterized.

Boundary conditions significantly influence plasma behavior.

Abstract

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.
