Using metasurfaces, light can be manipulated beyond the limitations of classical optics. For instance, metasurfaces are used to widen the antenna aperture, to tailor light polarization, to be transparent, etc. Here, we study the effective fields in a magnetoelectric dipolar lattice positioned near PEC substrate. We show analytically that in the case of a subwavelength lattice spacing, the coupling between the electric and magnetic dipoles is induced mainly by the substrate reflected fields of dipoles at the coordinate of the perspective centre.
