Sažetak
This chapter deals with boundary integral equation methods for the assessment of the human exposure to electrostatic, low-frequency (LF), and high-frequency (HF) electromagnetic fields. The formulation for the LF exposures is based on the quasistatic approximation and the related Laplace equation form of the continuity equation. The assessment of HF exposures is based on the Helmholtz equation, coupled surface integral equations, and volume tensor integral equation. The solution of the governing equations is carried out using certain boundary element procedures, hybrid finite element/boundary element approach, and method of moments. A number of illustrative computational examples are given, pertaining to the human head exposed to electrostatic field from video display units, pregnant woman/fetus exposure to extremely low-frequency fields from power lines, the human eye and brain exposed to HF electromagnetic radiation, and the whole body exposed to radiation from base station antennas.
