Terahertz (THz) band refers to the frequency range covering roughly 100 GHz – 10 THz. Located between microwave and optical bands, THz band has been less explored compared to these widely developed neighboring bands. Recently, however, THz band is attracting growing interests owing to its potential for exciting applications such as broadband communication and high-resolution radar systems, which has been further fueled by the recent advancement in high-frequency semiconductor technologies. In this talk, a review of the properties of THz band will be provided and various THz applications will be overviewed. Then, an introduction to recently developed THz integrated circuits as well as THz imaging experiment based on the developed circuits will be presented. 

Biography:

Jae-Sung Rieh received the B.S. and M.S. degrees in electronics engineering from Seoul National University, Seoul, Korea, in 1991 and 1995, respectively, and the Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor, MI, USA, in 1999. In 1999, he joined IBM Semiconductor R & D Center, where he was responsible for the development of high frequency SiGe HBT technologies. Since 2004, he has been with the School of Electrical Engineering, Korea University, Seoul, Korea, where he is currently a Professor. He was a visiting scholar at Submillimeter Wave Advanced Technology team (SWAT) in JPL, Pasadena, USA, in 2012, and at High Speed Electronics Lab (HSEL) in UCLA, Los Angeles, USA for 2018-2019. His major research interest lies in the mm-wave and terahertz devices and circuits. Dr. Rieh was a recipient of IBM Faculty Award (2004) and a co-recipient of IEEE EDS George E. Smith Awards (2002 and 2006) and IEEE Microwave and Wireless Component Letters Tatsuo Itoh Best Paper Award (2013). He has served as an Associate Editor of the IEEE Microwave and Wireless Components Letters (2006-2009) and the IEEE Transactions on Microwave Theory and Techniques (2010-2013). He is the author of a book, “Introduction to Terahertz Electronics (Springer Nature, 2021)”. He is a Fellow of IEEE.
