About Chunyin Qiu
Dr. Qiu is currently a Professor in the Department of Physics, Wuhan University. He received a B.S. in 2002 in Wuhan University and a Ph.D. at the Hong Kong University of Science and Technology. His current research interest is to find novel acoustic phenomena in artificial structures. He proposed the concept of valley degree of freedoms for acoustics, and presented the first topological valley transport in the acoustic platform.
In our daily life, two fundamental wave phenomena, reflection and refraction, are naturally observed at an interface separating different homogenous media, which are interpreted by the well-known Snell’s law.
