Abstract (in Japanese) (See Japanese page) 
(in English) In the measurement of the specific absorption rate (SAR) of the wireless mobile device, the electric field probe is scanned in the phantom liquid and the SAR distribution produced in the phantom liquid is measured. It is necessary to calibrate the probe or to relate the electric field intensity at the tip of the probe to the combined output voltage of the probe. In frequency bands used in mobile phones, the calibration of the probe is generally carried out in a waveguide well filled with phantom liquid. In this report, we propose a method of determining appropriate ranges to fit the combined output voltage to the corresponding exponential decay function. We also discuss how to compensate the boundary effect superimposed on the combined output voltage near the bottom of the waveguide well.
