Systematic Design of a Holographic-Based Metasurface Reflector in the Sub-6 GHz Band.

This letter presents a systematic method to regulating the response of an artificial impedance surface. The method is based on governing the dispersion diagram to control the depth of modulation so that a meaningful pattern of scatterers is obtained on the structure. The method is applied on a holographic-based large reflective metasurface to achieve a dual-beam radiation pattern with tilt angles of $\pm 45^{\circ }$ in the azimuth plane at $f=3.5$  GHz. The structure is fabricated and the measured data concur with the simulation results. [ABSTRACT FROM AUTHOR]
