Research Center for Electromagnetic Environmental Effects of SEU

Research Centerfor Electromagnetic Environmental Effects (E3) of Southeast University (SEU) originated from themajor of electronic equipment structure established in 1965, which is one of the earliest institutions to carry out electromagnetic compatibility teaching and research activities in China. In 1992, Electromagnetic Compatibility Laboratory of Southeast University was established, and Electromagnetic Compatibility Professional Test Center of Jiangsu Province was led to be established in 2005. In 2007, the lab was authorized by International Radio, Communication and Electromagnetic Association (iNARTE) as the Electromagnetic Compatibility Engineer Certification Training and Examination Center. After that, Nanjing "Wireless Valley" Electromagnetic Compatibility Public Technical Service Center of Jiangsu Province was established in 2010. In 2019, Research Centerfor Electromagnetic Environmental Effects of Southeast University was established based on the lab. There are more than 50 teachers and students in the research center, including 3 professors, 3 associate professors. Two of them are the experts with special government subsidies from the State Council, and one of them is high-level scientific and technological innovation talent. There are more than 40 doctoral and master students here. The center has strong scientific research capability and profound technical foundation in the field of electromagnetic environmental effects, and has advanced research platforms and experimental conditions such as 5M semi-anechoic chamber, electromagnetic reverberation chamber, electromagnetic protective material performance laboratory, electromagnetic environment simulation laboratory and open area test site.

Guided by major national strategic demand such as intelligent manufacturing, new energy vehicles, advanced aerospace and equipment construction, the Center is committed to scientific issues, basic theories, key technologies, standards and applied technology research and cultivation of talents in the field of electromagnetic environmental effects. With the background of "mechanical electronics", the center combines structural design with electromagnetic compatibility theory, and has remarkable disciplinary characteristics in the research of effects under electromagnetic, thermal, mechanical vibration and corrosion and other multi-environmental influences, electromagnetic compatibility standard compliance testing technology and standard formulation. TEM Cell, GTEM Cell, electromagnetic reverberation chamber, absorbing material performance test device, material and cable shielding performance test device and a large number of test equipment with independent intellectual property rights were self-developed, forming a material electromagnetic compatibility and protection performance test capability. In recent years, the Center has presided over more than 40 national strategic industrial projects in the fields of new energy vehicles, smart grid and communications, presided over and participated in the formulation of more than 20 national standards for electromagnetic compatibility, and won 8 provincial and ministerial scientific and technological progress awards.
