Professional Service
Selected Invited Presentations
Ho-Jin Song received the B.S. degree from Kyungpook National University, Korea in electronics engineering in 1999 and the M.S., and Ph. D. degree in information and communications engineering from Gwangju Institute of Science and Technology (GIST),
Korea, in 2001, and 2005, respectively.

From 2005 to 2006, he was involved in the Center for Hybrid Optical Access Networks (CHOAN) in the GIST, Korea, as a research professor, and engaged in research on radio-over-fiber technologies cooperating with Local Multipoint Distribution Service
(LMDS) wireless systems operating at millimeter wave frequencies of 26 and 29 GHz and development of long-distance
microwave transmission system operating at 8 – 10 GHz for relaying broadcasting signals. Since he joined NTT Microsystem
Integration Laboratories, Nippon Telegraph and Telephone Corporation (NTT), Atsugi, Kanagawa, Japan, in 2006, he has
been working on the development of millimeter-wave and sub-terahertz wave systems for communications, sensing, imaging,
radar and measurement applications operating at above 100 GHz utilizing both of high speed electronic and photonic
technologies. From 2013, he has been a Manager of the terahertz analog IC group and working on high speed/frequency analog ICs and their applications in optical and wireless communications with Si/SiGe/InP technologies. In 2015, He was named as a distinguished research scientist of NTT Laboratories, of which total number doesn’t exceed 1 % of the total research staffs.

His research area covers millimeter and terahertz ICs based on InP, SiGe and Si-CMOS electronics, their packaging technologies, novel terahertz metamaterials components and photonic integrated circuit with Silicon photonic technology for a wireless communications, sensing, radar applications, and next generation optical communications transceivers. In addition, wireless front-haul network system and mm-wave RF frontend for 5G massive MIMO systems are also in his research interest.

He has more than 100 peer-reviewed international journal and conference publications in mm/THz-wave ICs, microwave-photonics, and the system demonstrations. He also hold more than 20 patents filed in Japan and Korea. Dr. Song was awarded the Best Thesis Award from the Gwangju Institute of Science and Technology, Korea (2005), Young Scientist Award of Spectroscopical Scoiety of Japan (2010) and Best Industrial Paper Award at IEEE MTTS-IMS2016 (2016). He was also the recipient of the Tatsuo Itoh Prize (2014) for the paper published in the IEEE Microwave and Wireless Components Letters in 2012. He serves the associated editor of Electronics Letter, IET from 2015 and the guest associated editor of the special issue on Terahertz Technology of IEICE Transaction of Electronics, to be published in December, 2015. He is also a member of technical committee in IEEE Microwave Theory and Technique Society (MTT-4, Terahertz Technology and Applications).
