The National Metrology Institute of Japan (NMIJ), the National
Institute of Advanced Industrial Science and Technology (AIST), Japan,
has a long history in research and development of high frequency
metrology standards. In this seminar, the research and development
activities in high frequency power standard and scattering parameter
(S-parameter) standards will be covered.
For the national metrology power standard – calorimeter, Dr Kazuhiro Shimaoka
will briefly present the recent study on dry-loaded calorimeters for
WR-10 and WR-15 rectangular waveguides (50 GHz to 110 GHz), and give a
short report on the current research on WR-6 rectangular waveguide
calorimeters (110 GHz to 170 GHz). Techniques in mm-wave power meter
calibration will be also discussed. Focus points are a thermal
feedback system (TFS) that enables very fast and stable calorimetric
measurement, and the evaluation of equivalence error of DC-RF
substitution. The TFS reduces the typical reading time per frequency to
less than 10 min, and the minimum measurable incident RF power is 0.2
mW. A new technique for reducing the equivalence error (EE) by
utilizing a flat mm-wave absorber is also discussed for the WR-10 and
WR-15 rectangular waveguides calorimeters. The recent work in NMIJ on
WR-6 rectangular waveguides calorimeters will be also presented.
NMIJ has launched the development of microwave scattering parameter
(S-parameter) standards and their evaluation technologies since 2002. Dr Masahiro Horibe
will briefly present the past highlights and give an overview of the
current NMIJ’s research activity on S-parameter at RF, microwave,
millimetre-wave and sub-millimetre-wave (terahertz) frequencies. The
latest research works in NMIJ on techniques for permittivity
measurements and on-wafer measurements are just launched. The recent
work achievement in NMIJ on a VNA measurement technique in waveguide
transmission lines at terahertz will be presented.
About the Speaker
Dr Kazuhiro Shimaoka
received his B.E. degree in mathematical science from Osaka Prefecture
University, Sakai, Japan, in 1989 and his Ph.D. degree in quantum
engineering from Nagoya University, Nagoya, Japan, in 2001.
He was with Sanyo Electric Co., Ltd. in 1989. In 2002, he joined the
National Metrology Institute of Japan (NMIJ), National Institute of
Advanced Industrial Science and Technology (AIST), Tsukuba, Japan,
where he is currently a Senior Researcher and the calibration authority
of radio frequency power and voltage standards. He is also a Technical
Advisor to the Radio Frequency and Electromagnetic Field Subcommittee
of the Japanese Calibration Service System Committee, which is
organized by the International Accreditation Japan.
Dr. Masahiro Horibe
received his Ph.D. degree in Quantum Engineering from Nagoya University
in 2001. He received a Japan Society for the Promotion of Science
Postdoctoral Fellowship during 1999-2001. During 2001-2003, he worked
on the research of high-temperature oxide superconductor applications
in Fujitsu Laboratories Ltd. and Superconductivity Research Laboratory,
Japan. In 2003, he worked on carbon - nanotube applications in Fujitsu
Laboratories Ltd.. He is now with the NMIJ-AIST, Tsukuba, Japan. He
works on the research and development of the metrology standards of
scattering parameters for coaxial, waveguide and on-wafer transmission
lines in RF, microwave, millimetre-wave and sub-millimeter-wave
frequencies. Recently Masahiro’s research is also focused on
permittivity measurements for materials.
