Congratulations to Caleb Sieck!  He has a publication of cover page for Science (journal) in January 2014!  Science (journal) is a world leading journal of scientific research with very high impact factor (over 31 in 2012).  The article shows the results of a circulator for sound, which sound can be guided to flow in particular directions, but not in the opposite directions.  Caleb was advised by Dr. Siu-Kit Lau on his MS degree in UNL in 2009 to 2013 for “Investigation of Sound Transmission through an Open Window into a Room“.  He is now studying his PhD in University of Texas at Austin with a topic related to metamaterials.
