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.
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.
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.
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.
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.
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.
WNCG Industrial Affiliates, faculty and students come together for an annual event focused on WNCG's greatest resource; a collection of some of the world's brightest students. Open House provides recruitment opportunities to Industrial Affiliate Members through close access to WNCG student research and resumes, as well as creates opportunities for one-on-one meetings with WNCG students.
Prof. Gustavo de Veciana, Cullen Trust Professor at the University of Texas at Austin and member of WNCG, has been appointed member of the Board of Trustees of IMDEA Networks Institute. The Board is the highest organ of governance, representation and administration of the Spanish research Institute.
