Modeling and Simulation of Electromagnetic Fields on Biological Cells Using the Transverse Wave Approach

Abstract

This paper investigates the electromagnetic (EM) interactions between biological cells and nanosecond Pulse Electric Fields (nsPEF), using the Transverse Wave Approach (TWA) and microstrip line technology for simulations. TWA allows for efficient modeling of complex EM wave behaviors in heterogeneous environments like biological tissues. The study explores both medical and industrial applications of nsPEF, focusing on cancer treatment, such as melanoma destruction, and food decontamination. Simulations of EM wave propagation through biological cells reveal key insights into how electromagnetic fields behave at varying distances between the microstrip line and the biological cell. The results demonstrate that strong coupling at shorter distances enhances the effectiveness of cancer treatments, while weaker coupling at longer distances provides a safe and efficient approach for industrial applications such as bacteria elimination. These findings emphasize the importance of optimizing distance and field intensity for specific applications and lay the groundwork for future developments in EM-based treatments and technologies.
