In less than 2 months, the IEEE RFID 2019 Conference will kick-off in beautiful San Diego, California. It is the 13 in the conference series and the 12-consecutive event that our group has attended. What started with an invite in 2008 to the Las Vegas conference by then TPC-chair Daniel Deavours has turned into an annual event for our group … and a haven for some of the best multi-disciplinary researchers in the IEEE community. Below is a list of the full-length papers that have been submitted over the years by our group (students bold-faced, as per GT curriculum vitae guidelines). There are 25 total papers to IEEE RFID (and 4 more to the related, international RFID-TA series):
Alhassoun’s Talk at IEEE CCNC 2019 on Retrodirective Fading
Senior PhD candidate Mohammad Alhassoun visited the 2019 IEEE Consumer Communications & Networking Conference (CCNC) in Las Vegas, NV. There he presented a paper on the unique small-scale fading properties of a retrodirective backscatter channel. These channels have garnered a lot of interest lately due to their low-powered, long-distance link capabilities, which excites the “Internet of Things” community. Below are the slides from the talk, entitled “Spatial Fading in Backscatter Channels: Theory and Models.”
WWB18: Magnetic Materials
This lecture provides a quick overview of magnetic materials (for more in-depth coverage, check out this undergraduate lecture on magnetic materials). The final segment discusses the use of some special magnetic materials in electronic article surveillance (EAS) systems and other RFID applications.
2012: The Helmet Sensor System
Chris Valenta and Bashir Akbar built a 5.8 GHz backscatter semi-passive system for detecting real-time shocks in helmets. The primary use was concussion detection in sports.
In 2012, students Chris Valenta and Bashir Akbar put together a prototype 5.8 GHz backscatter sensor that was able to pull real time shock sensing data from the helmet of a sports player. Using a reader mounted on the side of a field, the microwave backscatter system grabbed 6-axis accelerometer and gyrometer data from a low-powered, micro controller-based system that ran off of a small coin cell battery. Variations of this system would serve as the template of future microwave backscatter radios.
Fun fact #1: The project was sponsored at the time by a small start-up named Thingamagigawerks.
Fun fact #2: A video of the helmet system in action can be seen here.
