摘要：

It is shown that optical transmittance and the magnetooptical (MO) Faraday rotation in the heterostructure of a periodically perforated metallic layer attached to a smooth magnetic dielectric thin. lm demonstrate resonance dependences on the wavelength and magnetic-film thickness. It is possible to adjust geometrical and MO parameters of the system in order to get these resonance peaks close in wavelength and get enhanced Faraday rotation (by a factor of 5-10) along with sufficient transmittance (30-40%). The phenomenon is explained in terms of the excitation of the surface plasmon polaritons waves coupled with waveguided modes of the magnetic film. (C) 2006 Elsevier B. V. All rights reserved.
