Two-dimensional antennas that can create and steer narrow beams are of interest for modern communication systems. Here, the authors demonstrate a scalable antenna array design that performs these functions with fewer elements than standard approaches

An electronically scannable phased array antenna architecture is proposed with a drastically reduced number of active antenna elements. The proposed approach is based on the concept of Huygens’ metasurfaces, where the fields in a given region are c

The introduction of emerging technologies such as autonomous vehicles, broadband satellite Internet and 5G/6G cellular communication has motivated countless research efforts in millimeter-wave phased arrays, radar systems, and MIMO antennas. The bigg

In this paper some perspectives on Huygens’ metasurfaces for antenna beamforming are described. Both paired, as well as, single metasurface approaches are described for beamshaping of elementary feeding sources in close proximity. Such metasurfaces

Huygens' metasurfaces have demonstrated a remarkable potential to perform wave transformations within a subwavelength region. In particular, omega-bianisotropic Huygens' metasurfaces have allowed for the passive implementation of any wave transformat

Huygens’ metasurfaces have demonstrated great potential at manipulating electromagnetic fields at will. While omega-bianisotropy has allowed to design a single reflectionless metasurface for transformations that conserve local power, many applicati
