| Outline of Final Research Achievements |
It was examined the feasibility of the calibration method of the probe using a reference antenna which is required for implementing the method of inserting the probe into the tissue equivalent liquid, which is one of the methods for SAR (specific absorption rate) evaluation in MHz band.
By appropriately selecting the size of a shielded loop antenna (SLA), which is a reference antenna, as its near-field gain is constant, it is possible to estimate the the electric field intensity radiated from the reference antenna, and it was confirmed that it is possible to realize the probe calibration in tissue-equivalent liquid for SAR evaluation in MHz band.
