Antennas and Electromagnetics Group seminar – 17th October

When: Friday, October 17, 2025, 1:00 PM - 2:00 PM
Where: Hybrid mode: In-person: Peter Landin: PL 3.02 + Online , Mile End

We are fortunate to have a talk from Professor Jean-Charles Bolomey taking place on 17th October. The title of Professor Jean-Charles Bolomey’s talk is: “Fast, Low-Invasive Visualization of EM-Very NearField Distributions around Wireless Communication/Sensing Devices: From Anechoic Chamber to Microscop”.

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.

Speaker bio: Jean-Charles Bolomey is currently Professor Emeritus of Paris-Saclay University, France (PSU). After earning a Radio Engineering degree from Centrale Supelec (CS), he became full-time professor at PSU in 1976, furthering his research in a joint unit with the Centre National de la Recherche 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 dosimetry, Industrial-Scientific-Medical (ISM) and NDE/NDT applications, with a strong emphasis on innovative developments and technology transfer. His major contribution, based on the Modulated 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 European institutions and start-ups, engaging in technology transfer and prototype evaluation procedures in these fields. Professor Bolomey is an IEEE Life Fellow, AMTA Gilespie Fellow and Fellow of the Electromagnetic Academy. He is also a member of the EurAAP Working Group 5. He received numerous awards for his pioneering contributions to fast electromagnetic NF techniques, microwave 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.
