A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication ...

"This phenomenon has previously been observed only in optics," remarks Yoichi Nii, "so we are very excited to confirm that it extends beyond optics to other wave phenomena." Through theoretical ...

The discovery of asymmetric diffraction in acoustic waves opens new avenues for innovative communication devices, impacting classical and quantum technologies.

The study was published in Physical Review Letters ("Observation of Nonreciprocal Diffraction of Surface Acoustic Wave"). New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction ...
