Profile I am interested in the antenna theory and designs. Especially, the development of small antennas or wearable antennas are my centric themes. I have also considerable interests about the evaluation technologies of the bio-EMC (ElectroMagnetic Compatibility) which relates to these. Bio-EMC means the electromagnetic influence which the microwave radiated from the small wireless equipment gives to user's human body. Additionally, I am being interested in the RF-ID technology which will contribute to the automation and the accuracy improvement of the distribution control. Now, it is the theme about which I am enthusing most because both small antenna technology and EMC technologies are needed as for UHF-RFID (Radio Frequency IDentification).
Research Field(Keyword & Summary)
  1. (1)Bio-EMC

    The center problems of Bio-EMC are the measurement of electromagnetic exposure quantity and development of the exposure suppression technology. SAR (Specific Absorption Rate) is defined as a quantity of electromagnetic exposure. We have developed an original SAR measurement method.

  2. (2) UHF-RFID

    Recently, RFID systems are expected to serve as the distribution management system of the alternative to bar-codes. RFID systems are widely used in the distribution management fields because it can perform multifaceted inspection and recognition in a non-contact manner with wireless technologies.
