Abstract

In this presentation we explain how reflectarrays can be made “perfect”, in the sense that no power is scattered into unwanted directions. In particular, we present examples of impenetrable metasurfaces for anomalous reflection and beam splitting. We show that passive perfectly performing anomalous reflectors must be non-local and that this property can be realized by proper engineering the reactive impedance of the metasurface.
