Abstract(in English) A local SAR estimation method that uses a solid phantom and E-field probe is proposed. The method allows local SAR to be measured using a simple setup and procedures. This paper examines the effects of the hole in the solid phantom for E-field probe insertion and inaccuracy in setting the complex permittivity of the solid phantom on antenna input impedance and local SAR. The FDTD method is used to show that antenna input impedance and local SAR are unaffected by the hole in the solid phantom for E-field probe insertion. However, antenna input impedance strongly depends on the complex permittivity of the solid phantom and if local SAR is to be measured accurately, ±30%, the complex permittivity should lie in the range -20%≨Δε_r'≨+50% and -50%≨Δσ≨+60%. Experiments using 2 solid phantoms with defferent complex permittivities confirm the usefulness of the proposed method.
