Summary

While fast visualization of Electromagnetic (EM) field distribution is satisfactorily obtained by numerical modelling, it still constitutes a key challenge for measurements in a wide spectrum of demanding applications spreading from the early design and prototyping of antenna modules to final online fabrication and compliance testing of mass-produced connected devices. But recently, the rapidity of measurement has been improved thanks to several modalities exploiting either various interaction mechanisms between EM waves with adequate sensitive materials or the combination of standard Near-Field (NF) measurements with optimized sampling strategies and advanced wavefront post-processing techniques to retrieve Very-Near-Field (VNF) distributions. The aim of this paper is to provide an overview of these modalities and a global comparison of their potential in terms of rapidity, sensitivity, invasiveness and spatial resolution.

Biography

Jean-Charles Bolomey is currently Professor Emeritus of Paris-Saclay University, France (PSU). After earning a Radio Engineering degree from CentraleSupelec (CS), he became full-time pro-fessor at PSU in 1976, furthering his research in a joint unit with the Centre National de la Re-cherche Scientifique (CNRS). Since the early 1980's, his work has continuously focused on fast Near-Field (NF) methodologies, including antenna measurement, EMC/EMI testing, RF dosime-try, Industrial-Scientific-Medical (ISM) and NDE/NDT applications, with a strong emphasis on in-novative developments and technology transfer. His major contribution, based on the Modu-lated Scattering Technique (MST) and related RFID issues, led to earliest convincing proofs-of-concept of rapid NF measurement and imaging systems using modulated probe arrays.

In 1986, he founded SATIMO, a company specializing in microwave imaging, whose advanced prototypes would leverage the launch of the Microwave Vision Group (MVG) ten years later. He actively participated in several European collaborative programmes on microwave imagery, ranging from medical diagnostics and hyperthermia therapy control to industrial tomography and material processing. He has also contributed to the scientific advisory boards of various Eu-ropean institutions and start-ups, engaging in technology transfer and prototype evaluation pro-cedures in these fields.
Professor Bolomey is an IEEE Life Fellow, AMTA Gilespie Fellow and Fellow of the Electromag-netic Academy. He is also a member of the EurAAP Working Group 5. He received numerous awards for his pioneering contributions to fast electromagnetic near-field (NF) techniques, mi-crowave imaging and related applications. Remained an active figure in these areas, he was frequently invited to deliver keynote presentations and author review papers on the subject. He is currently broadening his interests to ward multi-physics EM-Thermal visualization modalities for low-invasive NF/VNF characterization and diagnostic of wireless communication and sensing devices.
