Influence of GSM900 electromagnetic fields on the metabolic rate in rodents

[摘要] The development of exposure devices for investigating possible effects ofmobile communication systems to non-restrained animals aims at a homogenousfield distribution in the area the animals occupy. In the presented 900 MHzexposure device a quite good field homogeneity of 5% (including thestanding wave contribution due to internal reflections) is reached in thecage region mainly by flattening the transverse field. For the standardwaveguide (WR1150) without dielectric sheets this value reads 14%. Thedesired maximal whole body specific absorption rate (SAR) of 4 W/kg in theDjungarian hamster model is achieved at an input power of only 3.7 W.
