Abstract

Abstract Summary: Assessment of Human-Body Exposure to Electromagnetic Fields

Overview: This study employs Monte Carlo simulations to examine the exposure of the human body to electromagnetic fields in the frequency range of 10 GHz to 1 THz.

Methodology: The research involves solving boundary value problems using one-dimensional Maxwell equations alongside a bioheat equation for a multilayer plane model. Dielectric properties were measured in vitro up to 1 THz at body temperatures.

  • The simulation assesses variations in skin transmittance and internal body temperature considering individual differences in tissue thickness.
  • Impact of adipose tissue's dielectric properties on temperature elevation was explored, noting discrepancies with previous findings.

Findings: The findings suggest that the dielectric properties of adipose tissue do not significantly influence temperature elevation at frequencies over 30 GHz. Potential risks such as skin burns from exposure to millimeter-wave and terahertz-wave frequencies were evaluated.

Conclusion: The study also discusses the alignment of the observed effects with international safety guidelines by ICNIRP, emphasizing potential health risks associated with electromagnetic field exposure.
