Analysis and synthesis of wideband scattered signals from finite-size targets - aspect independent radiofrequency analog footprint.

Developing a new generation of systems based on chipless radiofrequency labels, operating like radar targets, and compatible with functionalities that can’t be obtained with classical technologies like barcodes.

The need for information identification and capture is a matter of prime importance in modern societies. Every sectors of society rely on the identification of data exchanged, the updating of the data recorded on a tag and the measurement of physical parameters.

Key issues such as the way to reduce power consumption, to improve the communication quality-of-service and to enhance connectivity have recently come up for lots of industries. One important direction for researchers to consider is to develop battery-less, low cost tags for wireless identification and sensing.

Lots of improvements have been done in the past few years on communication systems, based on electronic devices where an integrated circuit is at the heart of the whole system. The democratisation of these chipped based systems like the radiofrequency identification (RFID) one will give rise to environmental issues in the future.

However, these improvements pave the way for the development of new concepts based on radar or reflectometry principles.

Our main goal is to show that it is possible to associate the paper based chipless label ID with other features like the ability to write and rewrite the ID, or a sensor function.
