    A Study of Conformal Metasurfaces on Passive Beam Steering for Arrays
    (North Dakota State University, 2022) Ge, Ruisi
    Beam-steering has drawn significant interest due to the expansion of network capacity. However, a traditional beam steering system involves active phase shifters and controlling networks which can be complex. This work proposes a passive conformal metasurface design on beam steering. The phase shifting is achieved by changing the curvature of a conformal metasurface. In addition, three conformal prototypes were fabricated and tested using different techniques such as 3D printing. The simulations and test results indicate up to 20° of beam shifting. This study can be extended to higher frequency bands for lower power consumption beam steering systems.
