WNCG Prof. Todd Humphreys and his group of researchers in the Radionavigation Laboratory made headlines in recent months with their major breakthroughs in centimeter-accurate positioning. A few of the students have already created a startup spin-off to push these breakthroughs in precise positioning to the mass market.

Imagine drawing a light painting using a phone’s antenna and GPS system. Imagine a world of virtual reality, where buildings are perfect replicas of their real-world counterparts, down to the exact height of a piece of gum stuck under a desk. Where a person cannot only see their location on the street but also the exact height and orientation of their mobile device in hand. This world of imagination and precise positioning is now becoming a reality, and through the efforts of WNCG students, even finding its way to market.

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.

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.
