Session Abstract
With the growing demand for 6G communication, automotive technologies, and artificial intelligence, modern electronic systems require high power levels exceeding hundreds of kilowatts and ultra-high data transfer rates beyond hundreds of Gbps. These advancements pose significant challenges for electric and RF designs, particularly in addressing EMC (Electromagnetic Compatibility) issues. Near-field measurement has emerged as a cost-effective and practical solution for pre-testing and pre-certification, especially when full-wave modeling and simulation become impractical due to the complexity of real-world applications. This workshop will introduce and showcase recent advancements in near-field scanning, covering fundamental measurement principles,fast and adaptive scanning techniques, efficient data acquisition and near-field modeling methods, and their engineering applications in EMC. Attendees from both academia and industry will benefit from expert insights into smart scan, probe compensation, robotic automation, and machine learning, offering efficient, reliable, and scalable solutions for EMC challenges.
Presentations
11:00am - 11:30am
Optimizing near-field measurement time and accuracy using an adaptive measurement approach
Time is a critical Industrial parameter for near-field measurement. This presentation illustrates how measurement time can be significantly reduced by using the adaptive measurement approach (SSAS algorithm) while ensuring very good measurement accuracy.
11:30am - 12:00pm
Robotic Near-field Acquisition using On-the-fly Scan Technique
Cheng Yang
Hamburg University of Technology, Germany
This talk presents an adaptive near-field acquisition approach that employs iterative on-the-fly (OTF) scanning guided by Gaussian Process Regression with Bayesian optimization, enabling high-speed, high-resolution near-field measurements for large-scale EMC testing.
