The Brillouin scatterings of electromagnetic waves spectroscopy is based on the inelastic scattering of electromagnetic waves by spin waves. Similarly, the Brillouin light scattering is based on the inelastic scattering of photons by magnons. The main problem of Brillouin light scattering is the relatively low efficiency of the scattering. Therefore it was suggested to solve this problem by using the nanoplasmonic system at the surface of magnetic film. The theoretical model of interaction of two kinds of plasmonic systems and oscillating dipole moment caused by scattering of photon by spin waves were proposed. The numerical calculations of conditions for Brillouin light scattering enhancing were made and optimization contour maps were built. The results of the calculations will be used to select the morphology of the nanoplasmonic coating of the ferrite-garnet film for further experimental studies on the enhancement of Brillouin light scattering Product Description popup.authors Valeriy Lozovski Oleksandr V.
