Uncertainty Quantification of Epithelial/Absorbed Power Density in 1-layered Planar Skin Model with Uncertain Tissue Electric Properties

This paper presents a stochastic approach to compute the absorbed power density (APD) on skin surface when exposed to radiation of halfwave dipole antenna. Skin tissue is modelled as 1-layered half-space with uncertain electric permittivity and conductivity. Formulation is based on numerical solution of Pocklington equation and corresponding field integrals. Stochastic Collocation (SC) method is used for uncertainty propagation in a black box manner. APD mean, variance, skewness, kurtosis and confidence intervals are computed at 10, 30 and 90 GHz for different antenna-body distances.
