Engineers and scientists at The University of Texas at Austin and the AMOLF institute in the Netherlands have invented the first mechanical metamaterials that easily transfer motion effortlessly in one direction while blocking it in the other, as described in the Feb. 13 issue of Nature.

This area includes the study of wave propagation ranging from ultralow frequencies to microwaves. It involves investigations of electrical geophysics, antennas and scattering, radar target identification, wireless communications, microwave and millimeter-wave integrated circuits, and guided wave devices and systems. The activities in acoustics involve research in transducers, atmospheric and underwater acoustics, and noise and vibration control.
Texas ECE postdoctoral researcher Yakir Hadad has been named the recipient of the Leopold B. Felsen Award for Excellence in Electrodynamics from The European Association on Antennas and Propagation (EurAAP). The award was originally established jointly by the University of Siena and the University of Sannio, funded through a donation from Michael and Judy Felsen in fulfillment of the last wishes of their father, Professor Leo Felsen (1924-2005). The main purpose of the EurAAP Felsen Award is "to keep alive Prof.
Texas ECE graduate student Guneet Kaur and her advisor Prof. Ali Yilmaz have received the 2015 IEEE Antennas and Propagation Society Ulrich L. Rohde Innovative Conference Paper Award on Computational Techniques in Electromagnetics.
Prof Neal Hall is one of eight Austin finalists in the SXSW Interactive Innovation Awards for an unprecedented hearing device that mimics a fly's super hearing power.
UT ECE graduate student Romain Fleury has been named the recipient of the Best Student Paper Award in Engineering Acoustics at at the 168th meeting of the Acoustical Society of America in Indianapolis for his work on "Non-Reciprocal Acoustic Devices Based on Spacio-Temporal Angular-Momentum Modulation.” Romain had already been named the recipient of the "Young Presenter Award in Noise" at ASA earlier last month.

UT ECE professor Andrea Alù and a team of researchers have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices, as reported in the latest issue of Nature Physics.
Romain and his supervisor Prof. Andrea Alù were recognized for the paper "Parity-Time Acoustic Metamaterials and Unidirectional Invisible Sensors."
Prof. Neal Hall and his graduate students have developed a tiny, low-power device that mimics a fly’s hearing mechanism.
A team of researchers led by Prof. Andrea Alù has built the first-ever circulator for sound. The team’s experiments successfully prove that the fundamental symmetry with which acoustic waves travel through air between two points in space (“if you can hear, you can also be heard”) can be broken by a compact and simple device.
In an interdisciplinary collaboration, researchers at The University of Texas at Austin’s Institute for Computational Engineering and Sciences (ICES) teamed up with material scientists to understand, explain, and exploit a specific microwave effect. The team’s results were recently published in Scientific Reports.
Until now, the invisibility cloaks put forward by scientists have been bulky devices - an obvious flaw for those interested in Harry Potter-style applications. However, researchers at The University of Texas at Austin have developed a cloak that is just micrometers thick and can hide three-dimensional objects from microwaves in their natural environment, in all directions and from all of the observers’ positions.
ECE professor, Dean Neikirk, just received funding for a 5-year program to use wireless sensors to identify failing bridges, lower the cost of monitoring those bridges, and improve the safety of new bridges. The $6.8M project addresses a chronic problem for the aging American highway infrastructure. According to the American Society of Civil Engineers, deferred maintenance has left one-quarter of the nation’s bridges deficient. Congress mandated 2-year inspections in 1971, but at least 17,000 bridges did not meet the requirement in 2008, including 3 out of every 100 freeway bridges.
Professor Hao Ling and his team are developing algorithms that would use radar to detect human activities inside an enclosed space, such as inside a building. The algorithms would convert the radar signals to virtual renderings similar to that of a video game. Eventually, the technology could end up in a device that could be mounted on a vehicle and would monitor activities in a building as it traveled down a street.
