Assessment of human exposure to RF energy in some real scenarios

This paper presents an approach to estimate the main characteristics (specific absorption rate (SAR), total absorbed EM power and temperature rise) related to human exposure to EM energy. The assessment is done numerically using a proprietary software package, which is based on the finite difference time domain (FDTD) method and the method of auxiliary sources (MAS) (used here for partially homogeneous models). The general goal is to provide an efficient and sufficiently accurate method to assess human exposure to EM fields in a wide frequency range and for different types of exposure conditions: far field exposure (from cellular base stations) and near field exposure (from personal wireless communication devices). Dependence of exposure on different posture and EM field distribution inside the body is considered.
