    • A method and device for calculating the Specific Absorption Rate (SAR) caused in a body by the electric field of a wireless communications device. The method involves using a model of a body, wherein the device is placed in proximity to the model and the electric field is measured at discrete points, including measuring the magnitude of the electric field at points of a first and a second surface of the model. By means of the measured magnitudes, the phase at said points is determined, such that the complex electric field at said points is determined. The complex electric field at said points is then used to determine the complex electric field in the model of the body. The complex electric field is used in order to calculate the SAR value caused by the device.

    • In an apparatus for measuring a specific absorption rate (SAR), a first near magnetic field distribution of a radio wave radiated from an array antenna of a reference antenna including a plurality of minute antennas is measured, and an SAR distribution with respect to the radio wave radiated from the array antenna is measured with a predetermined phantom. Then a distribution of a transformation coefficient null is calculated by dividing the measured SAR distribution by a square of the measured first near magnetic field distribution, a second near magnetic field distribution of a radio wave radiated from a measured radio communication apparatus is measured, and an SAR distribution with respect to the radio wave radiated from the radio communication apparatus is calculated by multiplying a square of the measured second near magnetic field distribution by the calculated distribution of the transformation coefficient null.

    • An apparatus for measuring the specific absorption rate (SAR) of a device (8) which generate electromagnetic fields. The apparatus includes a homogeneous solid spherical test phantom which has the average electrical properties of human tissue and at a defined distance from the surface contains a dipole probe which is positioned in such a way that the derived probe signal is proportional to the average SAR for 1 g or 10 g of tissue. The device to be tested, for example a mobile telephone, is guided past the surface of the phantom and turned until the instrument displays the maximum SAR value of the relevant limit.

    • A wearable electric field detector has a housing mountable on a user's person and including a sensing circuit responsive to an electric field to generate a signal which varies in proportion to the strength of the sensed field, and an alarm circuit coupled to the sensing circuit for producing an intermittent audible alarm signal, which has a repetition rate varying in proportion to the strength of the field, and a visible alarm signal. A mute circuit is manually activatable for selectively muting the audible alarm and then automatically reenabling it after a predetermined time period. The detector includes a manually-actuatable test circuit. There is no on-off switch, the detector being disabled by being disposed in a shielded carrying case.
