Low Cost Intelligent Reflective Surfaces Using Mechatronic Metasurfaces

초록

Intelligent Reflective Surfaces (IRS) is one of the revolutionary technology due to their capability to dynamically manipulate electromagnetic waves (EM). Those capabilities to achieve such characteristics are by incorporating active elements into the metasurface design. Although intelligent reflective surfaces are such a promising solution for future wireless communications, each unit cell of the metasurface requires at least one active device. This led to high costs, complexity in design, and signal disruptions. Here, we proposed intelligent reflective surfaces by utilizing mechanical actuators with beam-scanning capability. The proposed IRSs are designed based on the phase-modulated metasurface unit cell and by using the rotation of the unit cell and spatial gap of supercells, the reflected beam can be controlled. The gear matrix and power screw systems are introduced as the mechanical actuator. © 2023 IEEE.
