Dr. Etienne Perret participated in the 6^th International Conference on Smart and Sustainable Technologies that took place in Spilt and Bol (Croatia) on 8-11 September 2021.

During the technical session dedicated to RFID/IoT Devices/Approaches, he presented his latest accepted publication co-authored with Zeshan ALI “Notes on the Extraction of Aspect-Independent Parameters of Chipless RFID Tags”. This research has been undertaken in the framework of the ERC project SCATTERER ID.

ABSTRACT – The paper presents the extraction of aspect independent parameters for dual-L dipoles based chipless radio frequency (RF) identification (RFID) tags using spectrogram method using single measurement. The implemented spectrogram method is based on a single short-time Fourier transform (STFT) averaging window. The performance of the spectrogram method is compared to the matrix pencil method (MPM). A computational time comparison between the spectrogram method and MPM is presented.
