Fig. 2: Electromagnetic field distribution Re(Ex) inside a nanopillar of magnetic metasurface.

a, c The TE(0,1)-mode propagating in y-direction and b, d the TM(1,0)-mode propagating in x- direction, excited by p-polarized light with E = (Ex, 0, 0) at normal incidence. All the cross-sections are taken at the center of the nanopillar. One period of magnetic metasurface is shown. Images show the field distribution in a normal to sample surface plane: a, b images show the field distribution in the direction along the wave vector and c, d show the field distribution in a plane orthogonal to the wavevector of the modes.
