On the electromagnetic emissions from mobile telephones: standards, instrumentation and probes

Abstract

In this preliminary study we present the variability, in the axial direction, of the electrical field emitted from a cellular phone as function of the relative distance between the source (the cellular phone) and the probe at 5, 10, 15, 20, 30 and 50 cm. The reduction of the electric field intensity, due to presence of the human head between the source and the probe, at 50 cm of relative distance, was performed too. In this case we have detected a probably absorption of the head of about 60%.
