A doble-layer reconfigurable metasurface antenna controlled by varactor diodes is presented. The structure is composed by a sinusoidally modulated metasurface on top, which is backed by a uniform metasurface loaded with varactor diodes and designed to accurately control the phase propagation. Beam-scanning dictated by a single parameter is performed. Numerical results are reported, demonstrating the good performance in terms of beam shape and aperture field control.

Abstract
A doble-layer reconfigurable metasurface antenna controlled by varactor diodes is presented. The structure is composed by a sinusoidally modulated metasurface on top, which is backed by a uniform metasurface loaded with varactor diodes and designed to accurately control the phase propagation. Beam-scanning dictated by a single parameter is performed. Numerical results are reported, demonstrating the good performance in terms of beam shape and aperture field control.
