Distance between exposed object and exposure source
The exposure system consisted of two identical anechoic test chambers with dimensions of 1.2 x 1.2 x 1.2 m built as Faraday chambers with the inside walls fully covered with absorbing material. The antenna was at a distance of 45 cm, the E and H fields were parallel to the horizontal plane.
The signal was generated by a GSM data generator and a power amplifier and controlled by a power meter. All exposure experiments were accompanied by a concurrent non-exposure control (side-by-side chambers).
