1. Profile

The Electromagnetic Waves division covers the metrology standards for electromagnetic waves ranging from lower than 1MHz up to higher than 100GHzin frequency. We have developed and been keeping many kinds of standards. Some of them are developed by the original technology and others are prepared to be traceable to those of other national metrology Institutes. They are disseminated through calibration services in the JCSS (Japan Calibration Service System) scheme and NMIJ Calibration and Testing Services. Our activity includes technical development of new metrology standards and expanding the range of prepared standards, as well as verifying their equivalence by participating in international key comparisons led by CIPM and APMP.

The division started as a part of the NMIJ in 2001, when the NMIJ was established as national standards institute in the fundamental reorganization of the AIST. The division consists of two sections for metrology standards on electromagnetic wave. To be used by many technical engineers in industry, the technology obtained by our R&D for developing national metrology standards is offered in the NMIJ club activities of Radio-wave and EM field clubs. The detail will be seen in the homepages of these clubs linked from the page of each section.
