Beam steering by Huygens metasurfaces for sensing applications. This project aims to develop steerable radar systems for navigation sensors and surround monitoring in vehicles, using antennas operating in the millimetre-wave range, which have improved resolution and maintain long sensing distances. The boom in radar sensing technologies used for safety and comfort in cars has stimulated the need for cost-effective directional antennas for beam steering in sensing applications. This project will use the recently discovered concept of Huygens metasurfaces, which enable cost-effective devices with low transmission losses and strong tuning of beam-steering angle. The wider availability of such radars is expected to enhance collision prevention systems, adaptive cruise control and ultimately help create self-navigating cars.

用于传感应用的惠更斯超颖表面的光束转向。该项目旨在开发用于车辆导航传感器和周围环境监测的可操纵雷达系统，使用在毫米波范围内工作的天线，提高分辨率并保持长传感距离。用于汽车安全性和舒适性的雷达感测技术的繁荣刺激了对用于感测应用中的波束转向的具有成本效益的定向天线的需求。该项目将使用最近发现的惠更斯超颖表面概念，该概念使具有低传输损耗和强波束转向角调谐的成本效益高的设备成为可能。这种雷达的广泛应用有望增强碰撞预防系统、自适应巡航控制，并最终帮助创造自动导航汽车。
