Mohammad Azadifar joins the elite rank of IEEE Senior Members


Fischer Connectors is home to high-caliber professionals who inspire people at work. Mohammad Azadifar, Signal Integrity Engineer at Fischer Connectors’ R&D in Switzerland, is one of them. We are thus immensely proud to announce that Mohammad has been elevated to the grade of Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), the world's largest technical professional organization for the advancement of technology.

“Senior Member is the highest professional grade of IEEE for which a member may apply. It requires extensive experience, and reflects professional accomplishment and maturity”, IEEE President and CEO Susan Kathy Land wrote to Fischer Connectors’ R&D Product Design Team on April 26, 2021. “Only 10% of our more than 400,000 members have achieved this level. We are very pleased to have Mohammad Azadifar join the elite rank of IEEE Senior Members – both Mohammad Azadifar and you should be proud of the professional achievements that led to this recognition. We look forward to additional contributions and successful projects and discoveries made by or associated with our new Senior Member.”

Mohammad Azadifar has been an active member of IEEE since 2019, contributing numerous technical articles on various research topics such as Computational Electromagnetic, Lightning Physics, Metamaterials and Time Reversal Imaging – read below a short summary of his latest article on electromagnetic interference (EMI) source localization. Since 2020, Mohammad has been serving as the chairman of the chapter on Electromagnetic Compatibility, Antenna Propagation, and Microwave Theory and Technique of the IEEE Switzerland Section.

Mohammad is also an official member of the Commission E - Electromagnetic Environment and Interference of the International Union of Radio Science (URSI).

He holds a PhD degree in Electrical and Electronics Engineering at the Electromagnetic Compatibility Laboratory of the Swiss Federal Institute of Technology in Lausanne (EPFL), where he worked on the characterization of upward lightning discharges. In 2018, Mohammad and his team were able to photograph the first ever upward positive lightning flash recorded in the world (photo below). They furthermore studied the electromagnetic effect of lightning with earth and ionosphere, and received several recognitions by the scientific society as well as the prestigious Richard B. Schulz Best Paper Award of IEEE Transactions on Electromagnetic Compatibility (EMC).

In 2018, he joined the School of Management and Engineering of Vaud (HEIG-VD), Switzerland, for a European project called Lightning Laser Rod whose aim is to guide lightning in a channel made by filamentation.

In Fischer Connectors’ R&D center located in Saint-Prex, Switzerland, Mohammad Azadifar provides his expertise in signal integrity engineering to advance connectivity technology in various high-speed data transmission and EMI/EMC projects.

Congratulations to Mohammad for the professional achievements that have led to this international recognition as IEEE Senior Member!

Summary: “A Compressive Sensing Framework for EMI Source Localization Using a Metalens Structure: Localization Beyond the Diffraction Limit”, Azadifar et al., IEEE Transactions on Electromagnetic Compatibility, 2021.

Modern electronic devices are shrinking in size to achieve higher data rates and to reduce power consumption. Various components on a printed circuit board (PCB) can radiate radiofrequency (RF) pulses, causing electromagnetic interference (EMI) with other components. Finding the source of the EMI source on a complicated PCB boards is thus one of the main challenges for PCB troubleshooting.

In this article, Azadifar et al. proposed a novel approach for the localization of EMI sources based on the concept of negative indexed metamaterial (Metalens), computational imaging and compressive sensing. Strongly coupled resonant rods were used to provide negative refraction below the plasma frequency of the structure. The proposed method does not need rasterized scanning and overcomes the diffraction limit, offering super resolution by transforming the evanescent wave in the vicinity of the source to a propagating wave to be picked up with a far field receiving antenna.

About IEEE

IEEE, pronounced "Eye-triple-E," stands for the Institute of Electrical and Electronics Engineers. An association dedicated to advancing innovation and technological excellence for the benefit of humanity, it is the world's largest technical professional society. It is designed to serve professionals involved in all aspects of the electrical, electronic, and computing fields and related areas of science and technology that underlie modern civilization.

IEEE's roots go back to 1884 when electricity began to become a major influence in society. There was one major established electrical industry, the telegraph, which since the 1840s had come to connect the world with a data communications system faster than the speed of transportation. The telephone and electric power and light industries had just gotten underway. More in History of IEEE
