The mission of this project is to, first, study the fundamental problem of electromagnetic energy exchange between an on-body wavefront-shaping structure and a microimplant in a complex biological environment and, second, to develop novel solutions for localization and adaptive wireless powering.


In close collaboration with other team members, the candidate will contribute to the prototype development, manufacturing, and testing. Last generation of high-performance workstations with GPU accelerators and advanced numerical solvers will be used to handle electromagnetic analysis. State-of-the-art manufacturing and measurement facilities of IETR will help with the prototyping and testing. The final system will be characterized in tissue-equivalent models as well as in vivo through established collaborations of our group. Finally, the successful candidate will be expected to present results of the work in high-profile journals and conferences.


— Ph.D. (or equivalent) degree.
— Full competence in electromagnetics and wave physics; knowledge of microwave and antenna engineering.
— Solid experience with numerical electromagnetic solvers (e.g., COMSOL, CST, HFSS), skills in programming (Python or MATLAB) and basic measurement equipment (VNA, etc.).
— Fluency in English: the candidate should be conversant and articulate in English and must have strong writing skills. Knowledge of French is not required but would be appreciated.

Work Context

Emerging in-body bioelectronics and biosensors offer powerful capabilities for medicine, clinical research, and basic science. Precision medicine requires precision diagnostics, and biotelemetric microimplants make it possible to yield more precise information than ever before about one's health. Neural interfaces allow us to study the brain via mapping, assist¬ing, augmenting, and repairing cognitive or sensory-motor functions. The emerging electroceuticals aim individual nerve fibers or specific neural circuits that regulate the body's organs and processes to treat a range of conditions. Many of required technological advancement is already in place thanks to advances in a variety of dis¬ciplines. However, modern microimplants suffer from the compromise between the size of the battery and the duration of the experiment or functionality of the device. Moreover, the battery replacement requires going through surgery. Therefore, the efficient through-body wireless localization and powering became a grand challenge. The qualified candidate will work towards solving the scientific questions in this field. This project builds on the unique scientific and technical expertise of the IETR laboratory (CNRS) in the fields of wave physics, complex radiating structures, and bioelectromagnetics.
