Metasurfaces for near-field wave control and coupling of light into fibers

Speaker: Dr Oleh Yermakov, V. N. Karazin Kharkiv National University, Ukraine
Date, Time: 11.05, 15:00 - 16:00

This research focuses on the study of resonant metasurfaces which are two-dimensional periodic arrays of the subwavelength scatterers engineered for the efficient light control. Namely, we aim to review:
(i) the dispersion and polarization properties of surface electromagnetic waves at anisotropic (in particular, hyperbolic) metasurfaces [1-4];
(ii) the polarization TE-TM degeneracy at all-dielectric [5] and self-complementary [6] metasurfaces;
(iii) the light collection of light into the single-mode fiber covered by the axial-symmetric metasurface [7,8].
