Abstract

Overview

Numerical investigation of the interaction between electromagnetic fields and eukaryotic cells requires specifically adapted computer models. These models help in understanding how electromagnetic fields interact within cellular structures in detailed and precisely measured environments.

Methodology

• A method is presented using 3D models via a virtual, finite element method-based capacitor experiment.
• The experience encompasses a frequency range from 10 Hz to 100 GHz, evaluating different shapes (spherical and ellipsoidal) and internal complexity (i.e., different organelles).

Findings

The investigation focuses on the current and loss distribution within cell compartments and studies the effects of dispersive material properties and geometric characteristics of the cell model. Specifically, the investigation revealed for 5 G frequencies, cell membranes significantly contribute to absorption losses, indicating potential risks in electromagnetic field exposure.

Implications for EMF Safety

Understanding the specific distributions of electric fields and current densities and how electromagnetic energy is absorbed by cellular components as revealed in these results could have important implications for refining safety standards in electromagnetic field exposures.
