Modulated metasurface antennas and beam-formers for mm-waves and beyond

Modulated metasurfaces (MTSs) can be efficiently used to guide the propagation of surface-wave (SW) wavefronts or to gradually radiate the power carried by a SW. These two complementary mechanisms can be applied, respectively, to design beamformers and antennas capable of addressing some of the needs in emerging millimeter wave wireless and future net-works beyond 5G. More precisely, we will present the use of modulated metasurfaces for the design of high-gain antennas and broadband beamformers. We will also show how the later can be efficiently combined with the former to provide multi-beam operation.
