Lighter, Cheaper Radio Wave Device Could Transform Telecommunications

Nov. 10, 2014
Researchers at the Cockrell School of Engineering at The University of Texas at Austin 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. The new circulator has the potential to double the useful bandwidth in wireless communications by enabling full-duplex functionality, meaning devices can transmit and receive signals on the same frequency band at the same time.

Prof. Andrea Alù and Team Build First Nonreciprocal Acoustic Circulator: A One-Way Sound Device

Jan. 30, 2014
A team of researchers in the Department of Electrical and Computer Engineering at The Unversity of Texas at Austin (UT ECE) 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.

Prof. Joydeep Ghosh Gives Keynotes at WDDL2013 and DMH 2013

Sept. 3, 2013
Prof. Joydeep Ghosh of UT ECE was the keynote speaker at the inaugural Workshop on Divergences and Divergence Learning (WDDl), held in Atlanta, June 2013. In his talk, entitled "Learning Bregman Divergences for Prediction with Generalized Linear Models," which reflects joint work with ECE and WNCG student Sreangsu Acharrya,  an efficient approach to learning a broad class of predictive models was introduced. What is most remarkable about this approach is that model parameters can be estimated even when the loss function is unknown.
