By controlling the surface reactance of impenetrable gradient metasurfaces it is possible to shape the phase front of reflected waves. This approach is similar to that used in conventional reflectarray antennas, where the phase of reflection from each array element is properly tuned. However, such phase-gradient reflectors always produce some parasitic scattering into unwanted directions. Here we present our recent results on non-local (spatially dispersive) gradient metasurfaces which do not have this drawback and demonstrate perfect anomalous reflection of incident plane waves into any desired direction.
