Structural Morphing Metasurface for Electromagnetic Beam Manipulation

Abstract: The paper presents a novel concept of a 3D structural metasurface with mechanically morphing capability that can be used as a transmit- or reflect-array to manipulate electromagnetic beams for applications in RF sensing and communications for both space and ground stations. They can be controlled using low-power actuators to deform the surface profile which is then utilised as a lens or a reflector for beamforming and steering. The proposed simulated structural metasurfaces can be used for either beam-steering or to generate bespoke contour beams for satellite communication and sensing.
