For the accuracy of Specific Absorption Rate (SAR) measurement, there is a need to have the measuring instrument, the E-field probe, calibrated on a regular basis, however, the conventional calibration approach can be complicated for an encapsulated dosimestic E-field probe. This paper proposed a new method to obtain the conversion factor of the E-field probe in the simulant tissue. The novelty of this proposal is that it can simplify the procedure of the conversion factor analysis, by employing the liquid waveguide with known E-filed as a component of the reference field to compare with the measured E-field of the dosimestic probe immersed in the equivalent-tissue liquid. Also, this paper evaluated the uncertainty of calibration for this method.
