Research Topics on RF Radiation and Propagation
Several research topics studied in the Antenna Laboratory at POSTECH for 30 years are introduced and briefly described. A unit cell of a metamaterial is designed and analyzed, and its propagation and attenuation constants are derived. Negative permittivity is observed for a narrow frequency band. A magic Tee is designed on a planar microstrip line combined with a slot coupling structure. A helical RFID structure is designed to identify a steel plate sandwiched between larger steel plates. Equivalent dipole current and loop current for the leaky noise radiation from an LSI chip are derived from measurement using a TEM cell. The Yun’s formula is established to calculate the resonance frequency of a coil for wireless power transfer. An equivalent circuit of a 3-port microstrip tee is developed accommodating the radiation loss from the tee.

Biography:
Wee Sang Park (M'89) received the B.S. degree in electronic engineering from Seoul National University, Seoul, Korea, in 1974 and the M.S. and Ph.D. degrees in electrical engineering from the University of Wisconsin-Madison, in 1982 and 1986, respectively. From 1986 to 1988, he taught at Wichita State University, Wichita, KS, as a Visiting Assistant Professor. He joined Pohang University of Science and Technology (POSTECH), Pohang, Korea, in 1988 and is currently a full Professor in the Department of Electronic and Electrical Engineering. Since 1995, he has been director of Antenna Laboratory of Microwave Application Research Center at POSTECH. Dr. Park is a member of the IEEE Microwave Theory and Techniques and Antennas and Propagation Societies. He is also a member of the Institute of Electronics Engineers of Korea.
