From December 2002 to November 2003, he was with the Institute for Pulsed Power and Microwave Technology, Research Center Karlsruhe (now KIT), Karlsruhe, Germany, where he performed the theoretical model and experimental verification of the microwave heating process of powdered metals. In December 2003, he returned to IECAS. From 1994 to 2002, his research activities were mainly devoted to high-power klystron development and millimeter-wave materials processing. He has authored/coauthored over 230 research papers in scientific journals and conference proceedings. His current research projects are the development of high-power gyro-amplifiers, klystrons, coupled cavity TWT, as well as microwave energy applications for material processing.
