Design of electromagnetic exposition system for irradiation of biological cultures

Design of an exposure system intended for irradiating biological cells with low frequency electromagnetic field in order to study impact of the electromagnetic field on the cells is reported in the paper. The purpose is to design the exposure system with high homogeneity of the magnetic flux density in a defined area of interest. Numerical simulations using CST Studio Suit are realized to adjust appropriate parameters of the system. The article presents how the input parameters influence the magnetic flux density distribution and its homogeneity. According to specified limitations appropriate design of the exposure system is reported and the results clearly show that the homogeneity reaches values of 99.97% in three of the five areas of interest.

I. Introduction

The research of the electromagnetic field (EMF) effects in the nonthermal frequency range on living cells is the worldwide longtime discussed topic. The ambiguity of results of various scientific teams urges to perpetually new ideas and solutions. Our group has been focusing on this issue for several years, e.g. [1]–[4]. However, the achieved results are ambiguous. There are still several open issues that need to be solved in order to get indubitable results [5]. Therefore, the next steps of our research are aimed at eliminating potential sources of uncertainties and unwanted influences - temperature fluctuations and low (<90%)homogeneous electromagnetic fields (with respect to the magnetic flux density thereof). Another potential source of unwanted influences represents high sensitivity of the system to the change of input parameters as e.g. the mutual layout of individual components of the experiment.
