Fast Scalar-Potential Finite-Difference Method with Human Model Based on Subgrid Method

摘要

There have been concerns about potential adverse health effects due to electromagnetic field exposure in low and intermediate frequency range. In the international guidelines by the International Commission of Non-Ionizing Radiation Protection (ICNIRP), the relationship between the allowable internal electric field and the corresponding external electromagnetic fields have been derived using anatomical human models. To accelerate the calculation speed and to improve accuracy for numerical dosimetry, we focused on the scalar-potential finite-difference method with subgrid method. In this study, we conducted the dosimetry for an anatomical numerical human model for uniform magnetic field exposure with the proposed method and post processing, and then demonstrated their effectiveness..
