Missions

With the upcoming massive deployment of 5G, new frequency bands have been introduced for wireless networking. According to the International Telecommunication Union (ITU), the mobile data traffic is expected to reach 5 zettabyte/month by 2030 and the number of devices connected to internet will exceed 75.4 billion by 2025. 5G exploits a large spectrum, ranging from frequencies below 1 GHz and the mid-band range (up to 6 GHz) to millimeter-wave (mmWave) frequencies. The adoption of the mmWave frequencies for mobile communications is a point of discontinuity with respect to legacy 2G/3G/4G generations. This results in the need to assess and analyse the exposure of the users to the electromagnetic (EM) field emitted by 5G devices, particularly for potentially more sensitive subjects, like children and pregnant women.

Activités

This project will build on our group's ongoing research into 5G sensors and dosimetry. The Research Fellow is expected to integrate the main current activities in our laboratory focusing on
1. The investigation 5G sensors and sources.
2. The development and test of the sensors impact on the human tissues in the presence of numerical and experimental phantoms mimicking the electromagnetic tissue properties.
The engineer will be expected to tackle the problem through a comprehensive approach, incorporating theoretical, numerical, and experimental techniques.

Compétences

Knowledge in electronics, signal processing, bioelectromagnetics, numerical modelling. Experience with commercial or open-source numerical solvers (e.g., CST, Ansys, SIM4LIFE, COMSOL Multiphysics) and programming skills (e.g., MATLAB, Mathematica) are welcome but not mandatory.
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.

Contexte de travail

The engineer will join Electromagnetic Waves in Complex Media Team (eWAVES) of the IETR/CNRS. IETR is one of the leading EU research laboratories in electronics, wireless communications, and digital technologies. Our research activities in biomedical electromagnetics cover a wide spectrum of fundamental and applied research spreading from multi-physics and multi-scale modelling to biomedical radars and advanced technologies for body-centric wireless communications. The team was at the origin of pioneering innovations in biomedical electromagnetics, including the first mmWave tissue-equivalent phantoms, novel reflectivity based surface phantom concept, new broadband multi-physics characterization technique for Debye-type materials, innovative mmWave textile antennas for smart clothing, ultra-robust miniature implantable UHF antennas, first mmWave reverberation chamber.
