She has presided over a number of horizontal projects of domestic enterprises. Participate in provincial and ministerial level scientific research projects and many horizontal projects of international / domestic enterprises as the principal researcher. She has published dozens of papers in domestic and foreign journals and academic conferences and won the third prize of electronic information science and technology award of China Electronics Society. She is the co-translator of the monograph "theory, technology and application of electrical contact“. And she has taught 10 undergraduate theoretical and practical courses and 3 postgraduate courses.
Abstract: The new requirements of 5g ecosystem for connecting system; the classification of high-speed interconnection components; the performance requirements of connectors; the structure of connectors; the signal integrity requirements of transmission lines; the research methods of transmission lines and the selection of simulation software. The differential transmission line has been widely used in the field of high-speed signals with its unique transmission characteristics, and it will be affected by many factors during the transmission process. In this paper, the differential transmission line is taken as the research object, and three-dimensional electromagnetic simulation software CST is used to investigate its signal integrity performance parameters including characteristic impedance, loss, and crosstalk. It is found through simulation that increasing the spacing between differential pairs will reduce the crosstalk. By reducing the length of the contact area, the smaller the return loss value, the smaller the TDR impedance value deviates from the normal value. The smaller the differential pair length, the greater the value of the insertion loss. This will improve the quality of signal transmission.
