Surface versus localized plasmons in an assembly of metal-dielectric parallel flat slabs in the presence of an in-plane magnetic field

Abstract

Closed-form exact expressions are derived for the macroscopic permittivity tensor of a parallel metal-dielectric sandwichlike composite microstructure in the presence of an externally applied static in-plane magnetic field. An exact closed-form expression for a magnetic-field- and structure-dependent resonance frequency of the multisurface plasmon is obtained. The optical properties of this plasmon are compared with those of the surface plasmons localized around cylindrical holes made in the metallic layers. All analytical results are verified by numerical simulations.
