Based on the trend of developments for modern electronic systems and combined with the characteristics of intelligence and interconnectivity in future electromagnetics information systems, this talk analyzes the importance of electromagnetic compatibility (EMC) and electromagnetic safety. The correlations between some commonly misinterpreted concepts are briefly introduced, including complex electromagnetic environmental issues and electromagnetic compatibility, electronic countermeasures and electromagnetic compatibility, electromagnetic environment adaptability and electromagnetic compatibility etc. The complexity of electromagnetic compatibility and electromagnetic security-related work is discussed. Next, from the electromagnetic interference (EMI) and EMC point-of-view, the connotation and correlation relationship of related basic concepts are introduced, which leads to the understanding that EMI is an inherent attribute, while EMC is the requirement of thresholds for EMI. The key technologies of EMI characterization and EMC quantitative design are then discussed. Based on EMI and EMC, the related concepts and logical relationships of electromagnetic environment effect (E3) and electromagnetic security are introduced. Finally, this talk analyzes the problems of EMI testing and E3 testing in the development of electronic information system, and proposes some suggestions to support the development in the field of EMC and electromagnetic security from the perspectives of talent training, fundamental research and major facilities layout.

Donglin Su received the B.Eng. and M.Eng. degrees of electromagnetic field and microwave technology, and Ph.D. degree of communication and information system from Beihang University, Beijing, China, in 1983, 1986, and 1999, respectively. From 1996 to 1998, she was a visiting scholar in the Department of Electrical Engineering, University of California, Los Angeles (UCLA). She currently is a professor in the Frontier Institute of Science and Technology Innovation and the School of Electronic and Information Engineering, Beihang University.

She has devoted herself to the field of electromagnetic compatibility (EMC) and electromagnetic environment effects for more than thirty years. Her main research interests include electromagnetic field and microwave technology, EMC and electromagnetic environment, and electromagnetic safety. In 2019, she was elected as the academician of Chinese Academy of Engineering.

Prof. Su is the director of the Ministry of Industry and Information Technology (MIIT) key lab of Electromagnetic Environment Effect (E3) for Smart System and Equipment at Beihang University. She also has several other professionals. For example, she serves as the chairs of the Expert Committee of the Electromagnetic Environmental Effects of Antennas Chapter of the Chinese Institute of Electronics, Beijing Chapter of the IEEE Antennas and Propagation Society, and the China Committee and Electromagnetic Field Theory and Application Committee of URSI (from 2011). In addition, she is the principle investigator for more than 30 research projects including the Key Basic Research of National Safety, Major Instruments Project of National Natural Science Foundation of China (NSFC), Key Program of NSFC, and many others.

We proposed the concepts of digital coding metamaterial/metasurface, in which the meta-atoms are represented by using digital states of phases. The digital representation of metamaterial/metasurface makes it possible to manipulate the electromagnetic waves and digital information simultaneously on the same platform, evolving a new direction of information metamaterial/metasurface. The information metasurfaces set up a bridge between the physical world and the digital world. Integrated with field programmable gate array (FPGA), the information metasurfaces can control the electromagnetic waves and process the digital information in programmable ways. By integrating artificial intelligence algorithms in FPGA, the information metasurfaces can perform intelligent tasks, yielding intelligent metasurface. In this talk, I will present some recent advances on the intelligent metasurfaces, including automatic designs of metasurfaces, intelligent microwave imaging, and intelligent microwave camera. I will also report to use several information metasurfaces to construct the convolutional neural networks, which can build up a programmable artificial intelligence machine.
