INFANTE MOREIRA, Pedro Severo  and  GILART GONZALEZ, Fidel. A 14-points array as a more realistic spatial averaging on the RF fields over the human body. EAC [online]. 2018, vol.39, n.3, pp. 16-30. ISSN 1815-5928.

Seven different arrays of points for spatial averaging of the RF field strengths in the frequency range from 100 MHz to 3 GHz were investigated through numerical simulations in a 2D planar environment under several multipath propagation conditions in connection with their goodness to express correctly the spatially averaged value over the planar area equivalent to that occupied by a standing adult human and a standing 6 year-old child. Of the two investigated new arrays of points the 14-points one was proposed since it yielded the spatially averaged values nearer than those obtained over the reference areas. In addition, it was demonstrated that this array of points can lead to better results compared to those recommended in the exposure guidelines and standards, as well as to others proposed in the literature.

Keywords : electromagnetic fields; human exposure; spatial average.
