Heterogeneous material blocking sound waves while transmitting electromagnetic waves (IMAGE)
Caption
Princeton University's Salvatore Torquato and Jaeuk Kim have demonstrated that the way these waves move through a heterogeneous material in turn elucidates characteristics of the material microstructure itself. The microstructure - the spatial arrangement of the different materials that comprise the heterogeneous material - impacts the way waves propagate. This schematic shows the heterogeneous material simultaneously selectively blocking sound waves but transmitting light, or more generally, electromagnetic waves.
