Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

Millimeter-wave radar is transforming safety in autonomous driving, but interference from other radars and jammers can compromise its reliability. New innovations like frequency hopping, metasurface ...

New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and ...

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Ship waves, the complex patterns generated as vessels displace water, remain a subject of significant scientific and engineering interest. Traditionally described by Kelvin’s theory of ship wakes, ...

Tim Kovachy is in the Department of Physics and Astronomy and at the Center for Fundamental Physics, Northwestern University, Evanston, Illinois 60208, USA. Quantum mechanics predicts that single ...
