Defu Wang received the M.Sc. degree in Electromagnetic Fields and Microwave Techniques from the Harbin Institute of Technology, Harbin, China, and the Dr.-Ing. degree in Electrical Engineering from RWTH Aachen University, Aachen, Germany. From 2010 to 2015, he was a Research Assistant with the Chair of High Frequency Electronics, RWTH Aachen University. In 2015, he joined the Circuit Design Department, IHP Microelectronics, Frankfurt (Oder), Germany, where he worked on the development of wideband submillimeter-wave systems for sensing and communications in 130 nm SiGe BiCMOS technology. From 2019 to 2021, he was with Center Nanoelectronic Technologies (CNT), Fraunhofer-IPMS, Dresden, Germany, where he is involved in the development of millimeter-wave circuits for communications and sensing in FD-SOI 22nm CMOS technology, and nonvolatile memory IP products in XFAB 180 SOI CMOS technology. Since 2021, he has been a Research Associate Professor of Carbon-based RF Electronics with Peking University, Peking, China.

Dr. Wang has served as a project leader at Fraunhofer IPMS-CNT for the joint project “T-KOS" – Terahertz technologies for communication and sensor technology, funded by Federal Ministry of Education and Research (BMBF), towards developing a German value chain for innovative THz technologies for communications and sensing applications. He was with the two leading research institutes from the Research Fab Microelectronics Germany (FMD).

Dr. Wang has continuously served as an oral presenter of the 2017-2020 IEEE MTT-S International Microwave Week (IMW). He also serves as a reviewer for the IEEE Microwave Magazine and the IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES.

Selected Works and Projects Since 2018:

1. 240 GHz and 500 GHz transceivers and on-chip terahertz sensing system in IHP 130 nm SiGe BiCMOS technology, and millimetre-wave radar front-ends in GF 22nm FD-SOI CMOS technology.

2. Participated in European projects of the ECSEL (BEYOND5, OCEAN12, WAKeMeUP) and two terahertz chip projects funded by the German Research Foundation (DFG) and the Federal Ministry of Education and Research (BMBF) (THz-LoC, T-KOS).
