Magnetic Fields Significantly Impact Sound Wave Movements in a Revolutionary Discovery

Researchers have discovered a novel way that surface acoustic waves interact with magnetic materials, leading to a surprising asymmetric diffraction effect. This could revolutionize acoustic-based communication technologies. Credit: SciTechDaily.comBy experimenting with nanoscale magnetic materials, researchers have uncovered an asymmetric diffraction pattern in surface acoustic waves (SAWs)—a phenomenon previously seen only in optics. This breakthrough...
