Abstract

Overview

This paper presents a comprehensive study on the effects of electromagnetic field (EMF) exposure on a honey bee. This research is crucial as it addresses potential health risks of EMF on living organisms, particularly at radio frequencies ranging from 2.5 GHz to 100 GHz.

Methodology

The study utilized numerical simulations employing the finite-difference time-domain (FDTD) technique to analyze the Specific Absorption Rate (SAR) in honey bee tissues. The main aim was to predict the potential adverse effects resulting from EMF energy absorption.

Key Findings

  • The honey bee was modeled as a 3-tissue heterogeneous dielectric object.
  • Sim4Life EM-FDTD solver was used for electromagnetic simulations.
  • SAR values of whole-body and brain tissue of a honeybee were determined and normalized to a 1 mW/cm² incident plane-wave power density.
  • Results indicated that EMF energy absorption varies based on the E-field polarization, frequency, and the peculiarities of the insect’s body.

Conclusion

The study emphasizes the importance of considering the frequency, E-field polarization, and physiological characteristics of organisms when assessing EMF exposure risks. These factors significantly influence the SAR values, implying potential health implications for the exposed organisms.
