Surrogate model based on polynomial chaos of indoor exposure induced from a WLAN source

This paper presents a statistical analysis of indoor exposure induced from a WLAN source. A surrogate model based on Polynomial Chaos method is proposed. The analyzed scenario consists of an anatomical model located in an unknowing position of a room of 3×4m
²
and a source located in a random position but near to the wall room. A computer experimental design based in a LHS method is proposed to cover at best the entire possible configurations. To calculate the exposure, a hybridize method combining the spherical wave description and the FDTD numerical method is used. 250 simulations had been performed and two surrogated models are presented.
