Chia-Lin Cheng and Luong N. Nguyen won the Best Poster Award at the IEEE International Conference on RFID 2018. Held from April 10-12 in Orlando, Florida, IEEE RFID 2018 is the world's premier science and engineering conference for RF identification and related technologies.
Cheng and Nguyen are co-advised by ECE Associate Professor Alenka Zajic and Computer Science Professor Milos Prvulovic, who are their coauthors on this work.
Cheng’s poster, entitled "Exploiting Switching of Transistors in Digital Electronics for RFID Tag Design," presented a novel RFID tag and a backscattering channel created by switching transistors in digital electronic circuits have been introduced. The proposed RFID tag is highly reconfigurable, can operate at carrier frequencies from 1 to 26 GHz, and reach distances of a couple of meters. This new backscattering channel opens up opportunities for fully digital antenna-less RFID tags.
Cheng and Nguyen work in the Electromagnetic Measurements in Communications and Computing Lab (EMC^2), which is led by Zajic. For more information about their work, visit http://alenka.ece.gatech.edu.
