Reconfigurable transmissive metasurface with a combination of scissor and rotation actuators for independently controlling beam scanning and polarization conversion

C. Lor, R. Phon, et al.

This fascinating research conducted by Chhunheng Lor, Ratanak Phon, and Sungjoon Lim presents a novel reconfigurable transmissive metasurface, enabling independent control of beam scanning and polarization conversion. With experimental evidence showcasing a remarkable 28° beam scanning range at 10.5 GHz for both RHCP and LHCP beams, this work promises exciting advancements in the field of wireless communications.

Abstract
This paper proposes a reconfigurable transmissive metasurface using scissor and rotation actuators to independently control beam scanning and polarization conversion. The metasurface, composed of rotatable unit cells, switches polarization between RHCP and LHCP by flipping the cells. Beam scanning is achieved by linearly changing the distance between unit cells using the scissor actuator. Numerical and experimental results show a 28° beam scanning range at 10.5 GHz for both RHCP and LHCP beams.
