The directional amplitude backscatter modulation with suppressed Doppler is demonstrated based on the scattering from a symmetrically rotating resonant loop. The concept is studied theoretically and ...

The high-speed rotation and complex operational environment of rotating bladed disks make it difficult for traditional contact measurement techniques to achieve effective, non-interfering, and ...

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large ...
