New insight into how waves spread in different kinds of artificial materials could shed light on how disorder affects quantum materials such as superconductors.

Since waves are used in all kinds of applications, from medical imaging to electronics, the physics behind disorder is fundamental to the understanding of how imperfections in the materials that compose these technologies affect wave behaviour.

"While disorder and imperfections are impossible to avoid in materials, there is much we do not understand about how disorder affects their properties," said co-author Brian DeMarco from the University of Illinois in the U.S., of the paper published in Science today.
