Scientists at the University of Southampton have experimentally proven the Zel’dovich effect by amplifying electromagnetic waves using a spinning metal cylinder, confirming a theoretical prediction from the 1970s and opening new avenues in technology and quantum physics. Credit: SciTechDaily.com
Their experiments demonstrated that the energy of waves can be amplified by bouncing ‘twisted waves’—waves with angular momentum—off a rotating object under specific conditions.
This is known as the ‘Zel’dovich effect’, named after Soviet physicist Yakov Zel’dovich who developed a theory based on this idea in the 1970s. Until now, it was believed to be unobservable with electromagnetic fields. READ MORE...
University of Southampton researchers have confirmed the Zel’dovich effect, where twisted waves are amplified by a rotating object. This finding, previously only demonstrated with sound waves, now applies to electromagnetic waves, with promising implications for quantum physics and energy-efficient technologies.
Physicists at the University of Southampton have successfully tested and confirmed a 50-year-old theory for the first time using electromagnetic waves.
