1 Laboratory Report of National Metrology Institute of Japan ( NMIJ / AIST ) and Japan Electric Meters Inspection Corporation ( JEMIC ) 2013 - 2015

At NMIJ/AIST, there are two divisions in the electrical standards area. One is the Electricity and Magnetism (EM) Division and the other is the Electromagnetic Waves Division. The former covers low frequency electrical standards and the latter high frequency and electromagnetic field standards. The EM division has two sections, the Applied Electrical Standards Section and the Quantum Electrical Standards Section. The Applied Electrical Standards Section takes charge of the AC/DC transfer, the high value impedance and the power standards. The Quantum Electrical Standards Section covers the Josephson voltage, the quantum Hall resistance, and the low value impedance standards. The Electromagnetic Waves Division has also two sections, the Radio-Frequency Section and the Electromagnetic Fields Section. The Radio-Frequency Section takes charge of RF power, voltage, noise, attenuation and impedance (S-parameter) standards. The Electromagnetic Fields Section covers antenna properties, electric field and magnetic field standards. One topic this year is that our old helium liquefier, which was also damaged partially, has been replaced, and the new system has started its operation in March 2014.
