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.
Two researchers at The University of Texas at Austin are making it possible for smart phone users on the Forty Acres to take a “Gander” at the digital space around them.

“The Invisible Man,” H.G. Wells’ 1881 novella, describes invisibility and invisibility cloaking concepts that are currently being explored and discovered at the Cockrell School of Engineering. Department of Electrical and Computer Engineering assistant professor Andrea Alú uses Wells’ story as a base for explaining his unique and innovative cloaking technique to make three-dimensional objects invisible. Alú takes “The Invisible Man” approach in his February TedxAustin talk.

Prof. Andrea Alù’s research on cloaking a three-dimensional object, making it invisible from all angles, for the first time, has received attention from the BBC News and other major news sources. The idea, outlined in New Journal of Physics, could find first application in high-resolution microscopes.
Prof. Alexis Kwasinski of UT ECE travels to the worst natural disaster sites around the world to assess the damage inflicted on communication networks and electric power grids. Dr. Kwasinski has surveyed the aftermath of three major Gulf Coast hurricanes, including Katrina, and stood in the rubble caused by earthquakes in Chile, New Zealand, and Japan.
UT ECE professor Andrea Alù and colleagues at the UT Applied Research Labs have successfully created a cloaking device capable of hiding a 3D object in free space from microwaves. To create the device, the team used a plasmonic metamaterial shell to cover the object being cloaked. The cloak, based on a plasmonic metamaterial, can hide a cigar-sized cylinder from microwaves – it currently only operates for one microwave polarization.
There has been tremendous interest in cloaking technology using metamaterials, and Andrea Alù's group in the Department of Electrical and Computer Engineering at The University of Texas at Austin, has been very active in the field, putting forward two exciting possibilities to obtain drastic scattering reduction from moderately-sized objects.
The human face does more than help us tell each other apart. Studies have suggested that our perceptions of attractiveness and personality traits — even intangible qualities such as trustworthiness and sincerity — could be based on instinctive responses to certain facial features.
But breakthroughs in facial recognition technology have been used in recent years to screen for criminals, to catch cheaters at casinos and even to recommend products at vending machines.

Femtocells will be assuming a massive role in expanding the capabilities of today’s cellular networks, and enabling them to satisfy people’s increasing demands for anytime, anywhere data. A femtocell is basically a small base station that people put in their home and attach to their wired internet connection just like a wireless LAN. However, it works just like a base station and seamlessly allows roaming, voice calls, and the increasing number of things people like to do with their cell phones.

UT-ECE’s Professors Sanjay Banerjee, Frank Register, and Emanuel Tutuc along with Prof. Allan MacDonald, UT Physics Department, and ECE graduate student Dharmendar Reddy designed a novel graphene-based BiSFET device that could revolutionize the chip design industry. This device is discussed in more detail in a recent IEEE Spectrum article.
Cell phone antennas, radio receivers and GPS devices may one day go incognito. In a paper to appear in Physical Review Letters, Andrea Alù and Nader Engheta propose a new cloaking method that cancels out the electromagnetic waves bouncing off an object. The concept may ultimately lead to surreptitious sensors that can collect and send messages without detection.
Professors Sanjay Banerjee and Emanuel Tutuc have demonstrated, for the first time, that centimeter-square areas of copper foils can be covered almost entirely with mono-layer graphene bringing this intriguing material one step closer to commercial viability. Graphene, formed with carbon atoms linked together like nanoscopic chicken wire, holds great potential for nanoelectronics. It also shows promise for electrical energy storage, for use in composites, for thermal management, in chemical-biological sensing, and as a new sensing material for ultra-sensitive pressure sensors.
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.
Dr. Mattan Erez's research focus is computer architecture. Specifically, he is interested in the critical aspects of locality, parallelism and bandwidth constraints to overcome the limitations of today's architectures. One goal is to improve cooperation between the hardware, compiler and programmer in order to enable new levels of performance, efficiency and code-portability.
Dr. Seth Bank's research into III-V compound semiconductors could cool down your laptop, increase the capacity and speed of fiber-optics, and make solar cells more efficient.

Professor David Pan and UT graduate students, Ashutosh Chakraborty and Anurag Kumar, took home the $25,000 Grand Prize in the eASIC Placement Design Challenge. The worldwide competition was to create a tool that determines the most efficient placement of components on a structured application-specific integrated circuit (ASIC) platform. Placement with shorter wirelength translates to better performance and less power consumption. Their placement tool, RegPlace, outperformed the second place team from the University of Michigan by 15% in total wirelength.
Dr. Robert Flake has discovered the first non-sinusoid signal that doesn’t undergo dispersion on transmission lines that would normally distort a signal.

University of Texas professors, Mack Grady and Surya Santoso, are another step closer to truly integrating wind power into the existing power grid. They are heading a consortium of private and public entities to create the first university-lead phasor measurement network in the country.
Professor Jake Aggarwal's research is in computer vision, specifically in smart surveillance systems that identify suspicious activity and alert humans to follow-up. His approach has evolved from the basic problems of determining movement of a 3-dimensional object from 2-dimensional images to a sophisticated system that can recognize aggressive activity even with multiple players and a cluttered background.
The tongue can be a powerful tool, but also a highly subjective one. Dr. Dean Neikirk developed what amounts to an artificial tongue. When food companies want to create the same flavor every time, they turn to Neikirk's electronic tongue to analyze liquids and pick out their exact chemical make-up. Neikirk's tongue uses microspheres, tiny sensors that change color when exposed to a specific targets, such as certain kinds of sugars. The result is a system that can't replace the person who says, This tastes good! but can make sure the chemistry of good taste is reliably replicated.
