摘要： An electromagnetic wave measuring apparatus includes a loop probe section having loop probes whose loop planes are placed so as to be perpendicular to each other, and each loop probe is placed so that its magnetic field detection space is not interfered with by other loop probes. If the loop probe section is placed at measurement position coordinates xi, yj, it detects a magnetic field component at the measurement position coordinates xi, yj, which is parallel to an XY plane, and a magnetic field component in a Z-axis direction at measurement position coordinates xi, yj−1, and repeats measurement by pitch p in a positive Y-axis direction. By calculating the root sum square of the detection results at each measurement position coordinate, a three-dimensional magnetic field level of an object to be measured can be obtained at each measurement position coordinate as electromagnetic field distribution with high-precision.

摘要： In an apparatus for measuring a specific absorption rate (SAR) for use in a radio apparatus, a first near magnetic field of a radio wave radiated from a reference radio apparatus is measured in free space, and an SAR of the radio wave radiated from the reference radio apparatus by using a predetermined phantom according to a predetermined measurement method. A transformation factor α is calculated by dividing the measured SAR by a square value of the measured first near magnetic field, and a second near magnetic field of a radio wave radiated from a radio apparatus to be measured is measured in free space. Then an SAR of the radio wave radiated from the radio apparatus to be measured is estimated and calculated by multiplying a square value of the measured second near magnetic field by the calculated transformation factor α.
