Outline of Final Research Achievements

Radio-frequency identification (RFID) technology that supports non-contact automatic recognition along with fast data reading, multi-target recognition and invisible recognition, is expected to be an essential component for realizing ubiquitous society. However, the electromagnetic fields from the devices, when they are employed in our living environment, raises concern that they may cause other electronic devices to malfunction due to electromagnetic interference (EMI). The EMI faced by active implantable medical devices (AIMDs) has become a very controversial issue in recent years.
A fundamental study on next generation tag interrogator which was applied mm-wave and superconducting filter technology was carried out in this research that was expected to achieve improved high-sensitivity and low-EMI capability from the stand point of AIMDs EMI issues in particular.
