Abstract:
An object of the present invention is to provide a simple way of measuring the local average absorbed power of a radio device having a plurality of antennas. A local average absorbed power measuring method of the present invention has an individual measurement step and a calculation step. In the calculation step, local average absorbed power candidates are obtained while weights are being varied. In a local average absorbed power candidate calculation sub-step, the absorbed power distribution in three-dimensional space is calculated from the combined electric field or combined magnetic field obtained in the combination sub-step, and a local average absorbed power candidate is obtained. In a local average absorbed power selection step, the highest one of the local average absorbed power candidates is specified.
