Description of the thesis topic

Context. Radiofrequency electromagnetic fields (RF) are widely used in civil and defense applications, for telecommunications, radar and electronic warfare in particular. Over the past decade, several collaborative research programs have been coordinated by WHO to assess the impact of these fields on the living. However, recent reports highlight a number of conflicting scientific results as well as strong questions about the consequences of exposure to RF waves on the living.

Abstract: Realized in partnership with industrials and the French Army General Direction – DGA -, the PhD investigation focuses on the development of a novel approach to evaluating the effects of RF waves on human cells in culture through the development of a metrology, which ensures calibrated conditions of electromagnetic fields application. RF devices, appropriate to the biological objects to evaluate, will be developed and tested by varying the different electrical stress parameters. This work will provide precise, quantitative data with respect to the dangers of non-ionizing electromagnetic radiation on the living.

The PhD objectives are :
o The design of the RF exposure module,
o The fabrication of this component,
o The experimental validation of cells RF exposure, including the evaluation of the Specific Absorption Rate -SAR- for different applied electromagnetic waves,
o And finally, the integration of this RF exposure setup into an instrumentation, in collaboration with our industrial partners.

This project combines interdisciplinary competences in the fields of radio frequencies, electronic and biology to develop a RF metrology adapted to the cellular scale.

Profile : The candidate should present an electrical engineering or physical background, with a strong interest in interdisciplinary researchs.

Work Context

LAAS-CNRS, MH2F team, Toulouse, France. The High Frequency and Fluidic Micro nanosystems team -MH2F- is located at LAAS in Toulouse, a CNRS laboratory, which has one of the 5 major micro- and nano-technologies clean room of France. Its expertise covers the miniaturization of RF systems as well as the operation of RF signals for new biological assay systems at the cellular and molecular level. The team is strongly involved in the committee dedicated to "Biological Effect and Medical Applications of RF and Microwave" of IEEE Microwave Theory and Techniques Society. The technical skills of members MH2F team cover the fields of design and RF metrology as well as of micro and nanotechnologies.
