Abstract:
The phenomenon of the electromagnetic field concentration in the near-field of the diffraction structures with two-dimensional periodicity consisting of a dielectric diffraction grating and a waveguiding layer is considered. It is shown that in the case of circular polarization of the incident wave the inverse Faraday effect can be significantly increased. The value of the inverse Faraday effect in the diffraction structure in more than 40 times higher than that for a homogeneous layer. Potential applications of the studied structures are connected with the possibility of local control of the magnetization and the field enhancement.

Key words:
nanophotonics, inverse Faraday effect, evanescent wave, diffraction grating
