<p>Imagine a radar system that doesn't just rely on linear waves but instead uses spiraling electromagnetic waves with orbital angular momentum (OAM). These special “vortex” waves have a helical twist and introduce a signature rotational Doppler effect when they encounter a spinning object. To improve identification and detection of these rotational Doppler effects, researchers from University of Shanghai for Science and Technology (USST) have harnessed terahertz (THz) waves by developing an integrated THz vortex beam emitter, as reported in the Gold Open Access journal <em>Advanced Photonics.</em> According to USST Professor Yiming Zhu, corresponding author for the article, “To the best of our knowledge, this study represents the first demonstration of an integrated THz vortex beam emitter specifically designed for the detection of rotating targets.”</p> ....
