Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. The technique, described by IMDEA Materials' Dr. Johan ...

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...
