Abstract (in Japanese) (See Japanese page) 
(in English) We focus on a novel calibration technique for an electric-field probe used in the standard evaluation of SAR (specific absorption rate) for mobile communication devices, in which we use the electric field distribution produced by a waveguide aperture operated in the tissue-equivalent liquid. In this report, we analytically derive an approximate expression for the electric field distribution near the waveguide aperture in the homogeneous lossy medium if the aperture is excited by its TE mode. The formulation is validated by measuring the electric-field distribution with a probe scanned in the liquid for the SAR evaluation at the frequency of 5200MHz. Moreover, we can find that measured CF (calibration factor) of the probe in our proposed probe calibration technique is well agreement with the manufacturer-supplied CF.
