This presentation will provide background information to consider when determining the optimal chamber design for varied applications. Since chambers involve a considerable investment, taking the time up front to weigh options for the best design is very cost-effective in the long run. Topics presentated include a review of EMC standards since the first task is generally to identify which standards the chamber will be used to test in accordance with. General design guidelines, performance simulation ability and accuracy, and optimizing a design for a limited space will be reviewed. Finally, with existing chambers, guidelines will be provided for those considering retrofitting a chamber with new absorber. Troubleshooting tips will also be provided should an existing chamber fail to meet performance expectations.
Demonstration Overview: A demonstration of the time domain measurement technique per the draft ANSI Standard C63.25 in a 3 meter semi-anechoic EMC chamber will follow the presentation. The live demonstration shows the effectiveness of the measurement process, the data post-processing, and analysis of the results. Time domain site VSWR is post-processed through statistical techniques, and data is shown to correlate to the CISPR method. Attendees will see how time domain measurements provide an efficient and cost effective way to validate chamber performance as well as indicate precisely where a chamber may have problems meeting performance expectations.
ABOUT THE SPEAKER
Dr. Zubiao Xiong is an RF engineer with ETS-Lindgren, located in Cedar Park, Texas. He obtained his B.Eng. and Ph.D. (both degrees in Electronic Information Engineering) from the Huazhong University of Science and Technology, China in 2003 and 2009, respectively. After that, he joined the University of Houston as a research fellow, focusing on the research of computational electromagnetics and its applications in biomedical engineering and electromagnetic compatibility. He developed the simulation software for predicting and analyzing the performance of anechoic chambers, and then joined ETS-Lindgren in September 2016. Dr. Zubiao Xiong is an active member of the working group addressing IEEE-STD-1128 on RF Absorber Evaluation. His current research interests include EMC and microwave chamber design, novel RF absorber material development, and time domain measurements for site validation and antenna calibration.
