Dr. Xiaolong Wang received the B.S. degree in communication engineering from Jilin University, Changchun, China, in 2005, and M.S. degree from Changchun University of Science and Technology, Changchun, China, in 2008, and Ph. D. degree from University of Toyama, Toyama, Japan, in 2012. From November 2012 to June 2013, he was with the Art, Science and Technology Center for Cooperative Research, Kyushu University, Japan, as a Post-Doctoral Research Associate. From July 2013, he was postdoctoral research fellow with the Plasma Research Center, University of Tsukuba, Japan. He is a member of IEEE (Institute of Electrical and Electronics Engineers, USA), IEICE (Institute of Electronics, Information and Communication Engineers, Japan) and JSPF (Japan Society of Plasma Science and Nuclear Fusion Research, Japan). He was the recipient of the IEEE MTT-S Japan Chapter Young Engineer Award in 2013. His research interests include microwave/millimeter-wave system design, passive component design and optimization techniques.
In this presentation, advanced microwave and millimeter-wave technologies for both components and systems will be presented.
Wilkinson power divider is a basic passive component and widely used in microwave and millimeter-wave systems. It can be analyzed by even- and odd-mode method which is a general analytic procedure in microwave theory. Based on emerging theories and technologies in recently years, various Wilkinson power dividers are designed for different aims. Industry applications are also included such as low cost, miniaturization, easy fabrication, and so on.
For system design, two projects: LIDAR system and diagnostic system for nuclear fusion will be presented. We have proved that new LIDAR system could provide 0.01 meter with real-time imaging. In nuclear fusion, there are diagnostic methods, such as gold neutral beam probe, microwave diagnostics, spectral diagnostics and Thomson scattering diagnostics. The basic diagnostic principle will be introduced, current situation of nuclear fusion research filed around the world is also considered, such as ITER in France and EAST in China.
The innovation of microwave and millimeter-wave technologies will pave the way for Terahertz range in difference fields such as high resolution and real-time imaging, wireless communication system, biomedical application.
