The research developed within the ORSYS (Optoelectronic and RF Systems) group considers signals and technologies for RF, including Wireless systems. Main projects focus on the design, optimization and characterization, as well as practical implementation. The ORSYS staff members have large expertise in applied Electromagnetism, and RF domains, as well as the integration and miniaturization of systems for communication and sensing. RFID and UWB technologies are among the most studied solutions. More recently metamaterials and nanotechnologies, due to their enabling properties, are part of our research projects.

The group has acquired many research facilities such as professional platforms for RF and Electromagnetic simulation in addition to several RF test and measurement setups including anechoic chamber.

The successful applicant will be joining the ORSYS group led by Prof. Etienne Perret, ERC grant holder, and the research aims associated to his ERC project untitled “Analysis and synthesis of wideband scattered signals from finite-size targets – aspect-independent RF analog footprint” (ScattererID) to develop the future of the chipless RFID technology. This two million euros project will employ around six team members during 5 years: 3 PhD students and a total of 9-year Post-Doctoral research position.



Project summary / Context and overview of the problem:


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. The ability to make objects interact with one another or with humans is an important factor in many applications, all the more so if this interaction can occur without human presence. The way to reduce power consumption, improve the communication quality-of-service and enhance connectivity has become key issues for lots of industries. Researchers need to consider the multiple factors simultaneously to design state-of-the-art RF devices for the next generation of identification services. One important direction is to develop low-power, low cost tags for wireless identification and sensing. Lots of improvements have been done today 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 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 approaches where the presence of the chip is not mandatory. These approaches are based on radar or reflectometry principles; these are non-invasive techniques but they require specific theoretical and practical developments. The difficulty is to be able to retrieve a small signal coming from a totally passive label placed in an unknown and movable environment. The objective of this project is to introduce the paradigm of RF communication system based on chipless labels, i.e. tags without any chip, bringing an ID, able to communicate with radio waves and having extremely low costs. This project aims at showing 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.


Main goals:


The main goal of the work (1st year) is to develop a measurement bench to characterize the RCS of chipless tag in 3D based on dedicated equipment specifically bought for the project. Relevant EM simulations will be done to estimate the performance and the accuracy of the bench.

The successful applicant will need to play a key role in the development of relationships with all the researchers (faculty members – post-docs – PhD students) involved in the project as well as help drive the research agenda.

The candidate should be capable of independent research with a structured approach to reporting and achieving goals.
