Biography

Takehiko Kobayashi received the B.E., M.E., and Ph.D. degrees in electrical engineering from the University of Tokyo in 1978, 1980, and 1983. He joined Nippon Telegraph and Telephone in 1983 and was engaged in research on various wireless communication systems.
He was guest scientist at National Bureau of Standard (now NIST) in Boulder, Colorado in 1986. From 1998 to 2001, he was with YRP Key Tech Labs, which focuses on the 4th generation mobile communication systems. Currently, he is a professor at the Department of Information and Communication Engineering, Tokyo Denki University. He received the IEICE Best Paper Awards in 2001 and 2002, and the Telecom System Awards from the Telecommunications Advancement Foundation in 2003 and 2005. His current research interests include ultra wideband wireless systems, mobile communication channel characterization, and teletraffic evaluation of mobile communication networks.

Sorting of Acrylonitrile-Butadiene-Styrene and Polystyrene Plastics by Microwave Cavity Resonance

By Yuya Mori Takehiko Kobayashi KenTahara

DOI: https://doi.org/10.5815/ijwmt.2016.02.01, Pub. Date: 8 Mar. 2016

This paper presents a new sorting method for acrylonitrile-butadiene-stryrene (ABS) and poly styrene (PS) by means of microwave cavity resonator perturbation. In this method, a small piece of sample material is inserted into a cavity resonator at a point when the electric and magnetic fields mark the maximum and the minimum values, respectively. Experiments were carried out with use of 1-, 2-, 5-, and 10-GHz resonators and ABS and PS samples of various sizes. Loss angles of polarizability (tan χ) exhibited differences large enough to achieve accurate sorting between ABS and PS.
