In this smart era, it is increasingly demanded to remotely monitor people in daily life using radio-frequency probe signals. However, the conventional sensing systems can hardly be deployed in real-world settings since they typically require objects to either deliberately cooperate or carry an active wireless device or identification tag. Additionally, the existing sensing systems are not adaptive or programmable to specific tasks. Hence, they are far from efficient in many points of view, from time to energy consumptions. https://phys.org/news/2019-11-intelligent-metasurface-imager.html Optics & Photonics Wed, 06 Nov 2019 08:33:50 EST news492251621 A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers.
