The main activities of the HIPE team are organized around the design, development, implementation, and operation of instrumentation tools in the spectral domain of microwaves. These instruments have several purposes:
to improve the understanding of wave propagation phenomena and their interactions with matter,
to characterize the electromagnetic behavior of active or passive components,
to explore the feasibility of microwave probing instruments in/with complex environments (direct and inverse diffraction, microwave imaging, etc.).
The realization of such microwave instruments requires a close coupling between both experimental and theoretical advances.
This is organized within the team according to several research axes:
the design and conception of dedicated measurement devices,
the measurement and calibration of electromagnetic fields,
the modeling of propagation and diffraction phenomena,
the development of inversion and imaging methods,
the determination of electromagnetic characteristics of materials.
All these research axes allow us to address concrete problems as a whole, such as the characterization of diffraction by complex objects (soot particles, aggregates, etc.), the measurement of radiation from innovative antennas or complex radiating structures, the improvement of measurement techniques (for example, by using the spectral properties of the measured fields or by focusing on optimal design), the development of robust imaging algorithms against noise, etc.
Finally, our expertise in the field of vector measurement of electromagnetic fields, in free or guided propagation, allows us to address many themes in connection with different laboratories or industrial partners.
