Electromagnetic Wave Metrology Group establishes national measurement standards for fundamental measurements of electromagnetic waves, including power, impedance, attenuation, RF voltage, noise, pulses, antenna characteristics, field strength, and material parameters of electromagnetic fields, covering a frequency range from sub-kHz to 1 THz. We also disseminate measurement standards and develop measurement technologies in related fields.
Building on these measurement standards and technologies, we focus on disseminating technologies required in national strategic technology areas such as next-generation communication, semiconductors, and aerospace to industries, academia, and research institutions. These research activities contribute to the sustainable development of our economy and the improvement of the citizens’ quality of life.
