Inaugural D-STOP Symposium Explores Pathways to Connected, Autonomous Transportation World

In 2013, 32,719 fatalities resulted from traffic crashes, most of which were caused by driver error. Across the globe, people are facing longer commutes and five Texas communities are in the top 26 most congested cities in the United States. Traffic congestion creates about 4.8 billion hours of travel delay and affects the environment through increased carbon footprints and higher fuel consumption.

Student Ahmed Alkhateeb Presents Invited Talk at ITA 2015 Graduation Day

WNCG PhD Student, Ahmed Alkhateeb, recently presented an invited talk during the Graduation Day at the Information Theory and Applications (ITA) Workshop 2015.

Graduation Day features outstanding graduate students and postdoctoral researchers seeking academic positions and provides them with an opportunity to present their work to a broad audience of researchers and faculty. They are the only ITA talks presented by students, and several past Graduation Day presenters have subsequently joined academic institutions.

WNCG Welcomes New Director for Three-Year Term

Every few years, WNCG welcomes a new Director and Associate Director from among its faculty ranks. With an academic culture that encourages openness and research collaborations among equals, the rotation of Directors provides each faculty member with the opportunity to lead WNCG.

Edison Series Brings Big Data to Middle-School and High-School Students

Just like Edison turned on the light bulb, the Department of Electrical and Computer Engineering (ECE) and the Wireless Networking and Communications Group (WNCG) at UT Austin are switching kids on to the field of engineering. Part of a STEM program geared towards middle school and high school students, the Edison Lecture Series celebrates fun over fundamentals and enables kids to have fun with science.

WNCG Introduces New Affiliate Membership Level

Effective February 2015, WNCG is pleased to announce the introduction of a new Level III membership option in its Industrial Affiliate Program. The Industrial Affiliate Program allows companies to become stakeholders in WNCG and to participate in the growth and direction of the center. Initially founded to significantly lower the cost of pre-competitive research for each sponsor, the program maximizes benefits to each sponsoring company.

Ultra-Thin Unidirectional Carpet Cloak and Wavefront Reconstruction With Graded Metasurfaces

Metamaterials and artificial materials with effective properties that may be controlled to a large degree have been at the basis of exciting schemes for wave manipulation and are particularly well suited to hide an object from electromagnetic waves. To realize practical invisibility cloaks, transformation electromagnetics (TE) methods and scattering cancellation techniques are currently the most popular approaches. Simplified versions of these proposals have been implemented and examined in recent years. 

Multiple Fano Interferences in a Plasmonic Metamolecule Consisting of Asymmetric Metallic Nanodimers

In this work, WNCG Prof. Andrea Alù, WNCG student Jing Bai and Prof. Khai Q. Le from Hoa Sen University in Vietnam theoretically explore signatures of plasmonic Fano interferences in a sub-wavelength-plasmonic metamolecule. Consisting of closely packed asymmetric gold nanodimers, these signatures lead to the possibility of generating multiple Fano resonances in the scattering spectrum. This spectral feature is attributed to the interference between bright and dark plasmonic modes sustained by the constituent nanodimers.

An Invisible Acoustic Sensor Based on Parity-Time Symmetry

Sensing an incoming signal is typically associated with absorbing a portion of its energy, inherently perturbing the measurement and creating reflections and shadows. Here, in contrast, Prof. Andrea Alù and students Romain Fleury and Dimitrios Sounas demonstrate a non-invasive, shadow-free, invisible sensor for airborne sound waves at audible frequencies, which fully absorbs the impinging signal, without at the same time perturbing its own measurement or creating a shadow.

Institute of Navigation presents Prof. Todd Humphreys with the Thomas L. Thurlow Award

Manassas Virginia, January 28, 2015 - The Institute of Navigation (ION) presented its Thomas L. Thurlow Award to Dr. Todd Humphreys at the ION International Technical Meeting (ITM)in Dana Point, California, January 26-28, 2015.

Dr. Humphreys was recognized for contributions that enhance radionavigation security and robustness in the face of intentional spoofing and natural interference.
