Jung Han Choi received the B.S. and M.S. degrees in electrical engineering from the Sogang University, Seoul, Korea, in 1999 and 2001, respectively, and the Dr.-Ing. degree from the Technische Universität München, Munich, Germany in 2004. From 2001 to 2004, he was a research scientist in the Institute for High-Frequency engineering at the Technische Universität München, Germany. During this time, he worked on the high-speed device modeling, thin-film fabrication, network analyzer measurement and circuit development for high-speed optical communications. From 2005 to 2011, he was with the Samsung Advanced Institute of Technology and the Samsung Electronics where he worked on the RF bio-health sensor, nano devices and RF/millimeter-wave circuit design including 60 GHz Si CMOS ICs. In 2011 he joined at the Fraunhofer Institute (Heinrich-Hertz Institute), Berlin, Germany. Now he is working on ultra-low power high data bit rate transmitter and receiver circuits for optical communications, microwave devices, electromagnetic simulations, and network analyzer measurement up to 170 GHz. In 2003, he was awarded for the EEEfCOM (Electrical and Electronic Engineering for Communication) Innovation prize 2003 for the contribution to the development of the high-speed receiver circuit. His current research interests range from microwave active/passive devices & IC, electromagnetic simulation & analysis, and metamaterials. He holds 18 international registered and 22 pending patents in the area of semiconductor device, circuits, and systems for high-frequency engineering. Krzysztof (Kris) Iniewski is managing R&D at Redlen Technologies Inc., a start-up company in Vancouver, Canada. Redlen's revolutionary production process for advanced semiconductor materials enables a new generation of more accurate, all-digital, radiation-based imaging solutions. Kris is also a President of CMOS Emerging Technologies (www.cmoset.com), an organization of high-tech events covering Communications, Microsystems, Optoelectronics, and Sensors. In his carrier Dr. Iniewski held numerous faculty and management positions at University of Toronto, University of Alberta, SFU, and PMC-Sierra Inc. He has published over 100 research papers in international journals and conferences. He holds 18 international patents granted in USA, Canada, France, Germany, and Japan. He is a frequent invited speaker and has consulted for multiple organizations internationally. He has written and edited several books for IEEE Press, Wiley, CRC Press, McGraw Hill, Artech House, and Springer. His personal goal is to contribute to healthy living and sustainability through innovative engineering solutions. In his leisurely time Kris can be found hiking, sailing, skiing or biking in beautiful British Columbia. He can be reached at kris.iniewski@gmail.com.
