Low frequency human exposure analysis for automotive applications

This paper presents a simulation methodology for efficient investigation of human exposure to low-frequency (1 Hz to 10 MHz) electromagnetic fields generated by automotive electrical systems such as wireless power transfer (WPT) systems. The main stages of the modeling process are discussed. A simulation approach based on the combination of computationally efficient methods such as surface integral equation (SIE) to handle 3D environment and volume integral equation (VIE) to simulate fields inside the human body model is used. TARO-based human body model is considered. For analysis of human exposure in different, realistic scenarios, human posing methodology is developed. Human exposure due to low-frequency magnetic fields of WPT systems is investigated. Inner body induced electrical fields are calculated and compared to ICNIRP basic restrictions.
