3D-printed device splits white noise into an acoustic rainbow without power
This article has been reviewed according to Science X's editorial process and policies . Editors have highlighted the following attributes while ensuring the content's credibility: The morphogenetical topology optimization method shapes the scattering inclusions, shown as gray material. When the ARE is excited by monopolar source emitting broad-band white noise, the radiated sound creates an acoustic rainbow. The source is positioned at the center of the emitter (illustrated using white light)
