Abstract Reconfigurable metasurfaces are man-made surfaces, which consist of sub-wavelength periodic elements—meta-atoms—that can be reconfigured to manipulate incoming electromagnetic waves. However, reconfigurable metasurfaces developed to-date

Reconfigurable metasurfaces are man-made surfaces, which consist of sub-wavelength periodic elements - meta-atoms - that can be reconfigured to manipulate incoming electromagnetic waves. However, reconfigurable metasurfaces developed to-date, have li

A circularly-polarized metamaterial leaky-wave antenna (LWA) at 5.5 GHz is presented, which exhibits zero beam-squinting (ZBS) at broadside with an increased gain. It consists of two oppositely-directed negative-refractive-index transmission-line (NR

The multibeam capabilities of a metasurface design that is enabled by an application-specific integrated circuit (ASIC) are presented in this work. The ASIC loads the metasurface with multi-bit discrete states, which translate into a finely tuned amp
