Danai Torrungrueng Author

Danai Torrungrueng received his B.Eng. degree in electrical engineering from Chulalongkorn University, Bangkok, Thailand, in 1993. He obtained his M.S. and Ph.D. degrees in electrical engineering from The Ohio State University in 1996 and 2000, respectively. From 1995 to 2000, he was a Graduate Research Assistant (GRA) in the Department of Electrical Engineering, ElectroScience Laboratory of The Ohio State University. Prior to joining Asian University, he worked as a senior engineer in the USA, involved in research and development of the urban propagation modeling project. At present, he is an associate professor in the Electrical and Electronic Engineering Department in the Faculty of Engineering and Technology at Asian University, Thai[1]land. In 2000, he won an award in the National URSI Student Paper competition at the 2000 National Radio Science Meeting in Boulder, Colorado. During 2004 to 2009, he invented and developed Meta-Smith charts (visit http://www.meta-smithcharts.org) for solving problems associated with conjugately characteristic-impedance transmission lines (CCITLs) and bicharacteristic-impedance transmission lines (BCITLs) graphically. His research interests are in the areas of fast computational electromagnetics, antenna design, RFID, rough surface scattering, prop[1]agation modeling and electromagnetic wave theory. He is currently a senior member of the IEEE and a member of the Electrical Engineering/Electronics, Computer, Telecommunications and In[1]formation Technology Association of Thailand (ECTI).
