Abstract

The public's concern over potential health risks related to the absorption of electromagnetic radiation (EMR) has been developing due to the prolonged use of cell phones close to the human body, particularly the human heart. To address these issues, this study aims to present a numerical simulation of EMR in the spectral range (900 MHz, 1800 MHz, and 2400 MHz) on human heart tissue using a Matlab program and the Finite-Difference Time-Domain (FDTD) method in One Dimension (1D). A mathematical analysis of electromagnetic radiation heating equations in a one-dimensional, one-layer model has also been discussed by numerically calculating the transient bioheat transfer equation and Maxwell's equations by using the FDTD to predict the effects of thermal physics properties on the transient temperature of human heart tissue. The results revealed that FDTD is an efficient method to evaluate the thermal effect of EMR due to its perfect boundary condition. It was found that the heart tissue reacts more at 900 MHz compared to 1800 MHz and 2400 MHz, and the tissue absorption is higher at the lower frequency. The effects of various parameters on the temperature increase in the human heart tissue were considered, such as the electric field, magnetic field, thicknesses, and thermal conductivity of the heart tissue. It was found that the frequency most affecting the tissue was 900 MHz. Our study found that the temperature distribution decreases with an increase in tissue thickness. We note that the results are similar for the different frequencies. It turns out that as the thermal conductivity of the heart tissue increases, the temperature distribution decreases slightly, while no change occurs here in the relationship between thermal conductivity and the temperature distribution of tissue with the change in the frequency of a wave.
