Statistical analysis and surrogate modeling of indoor exposure induced from a WLAN source

This paper is focused on the statistical analysis of thehuman indoor exposure induced by a WLAN source (often named “box”) located close to the walls human indoor exposure induced by a WLAN source (often named “box”) located close to the walls of a room of 3*4 m2. The exposure is firstly assessed by using a hybridize method combining the spherical wave description and the FDTD numerical method. A scenario, where the anatomical model is located in unknowing room position and the source is near to the wall but in an unknowing position is analyzed. Due to the variability of this scenario, the entire possible configurations cannot be calculated with the FDTD. A statistical method based on Polynomial Chaos is therefore discussed and used to build a surrogate model allowing to assess the exposure distribution.
