Abstract

The antennas and metasurfaces designed for biomedical applications operate primarily in the far-field rather than the near-field. Working in the near-field is considerably more intricate in both design and theory. Furthermore, the proposed methodologies are unsuitable for seamless integration with a radar system that seeks to offer an efficient and streamlined approach to achieve heightened sensing. Our research highlights the potential of metasurfaces in redefining radar-based sensing. By integrating metasurface principles specifically designed for near-field focusing into radar design, we unlock new possibilities for high-resolution biomedical sensing with real-time capabilities.
