Abstract

Abstract Summary

Overview

The study focuses on the increasing use of electromagnetic (EM) technologies in military applications to enhance battlefield communications and jam signals, utilizing high-power EM waves across various frequencies.

Methods

  • A numerical simulation evaluated the EM exposure of the human body near an HF vehicular antenna (2–30 MHz).
  • The antenna was modelled on a 3D vehicle structure with simulations including both, presence and absence of the human body.
  • Specific Absorption Rate (SAR) values were calculated under varied exposure scenarios, including a simulated protective helmet.

Findings

In proximity to the antenna, electromagnetic field (EMF) intensities potentially exceeded international safety standards. However, experienced SAR inside the human body was reported below the harmful limits, with a maximal local SAR value of 14 mW/kg.

Conclusion

Despite high EMF intensities near the antenna, the internal SAR values suggest minimal health risks under the simulated conditions. The study highlights the complex dynamics of near-field EM exposure in military settings and emphasizes ongoing compliance with safety guidelines.
