New Superlens Focuses Sound Waves

Our group have developed a novel acoustic superlens that focuses sound waves in much the same way that an optical superlens focuses light waves. In the May 15 issue of Physical Review Letters.  Zhang etc described the design and test results for an ultrasonic metamaterial lens that focuses 60kHz (~2cm wavelength) sound waves under water. The lens is made up of subwavelength elements and is therefore potentially more compact than phononic lenses that operate in the same frequency range. Made of metamaterial, the acoustic superlens technology, if improved, could lead to an acoustic cloaking device that might hide submarines and other objects from sonar. This work has also been reported by Technology Review.

NEW STAMPING PROCESS CREATES METALLIC INTERCONNECTS, NANOSTRUCTURES

Creating high-resolution metallic interconnects is an essential part of the fabrication of microchips and other nanoscale devices. Researchers at the University of Illinois at Urbana-Champaign have developed a simple and robust electrochemical process for the direct patterning of metallic interconnects and other nanostructures.Read More
