|Title||Numerical Study The Dielectric Properties And Specific Absorption Rate Of Nerve Human Tissue At Different Frequencies|
The study of electromagnetic radiation effects on human body is a very important subject, due to the possible health effects, these electromagnetic waves can cause in life tissue. In this paper, the dielectric properties and specific absorption rat (SAR) distribution in nerve human tissues exposed to electromagnetic radiation with different frequencies is studied. We modeled nerve tissue by layered system. Finite difference time domain (FDTD) computations were used to evaluator the electric, magnetic field, and specific absorption rate. Results show the dielectric properties as conductivity, relative permittivity and penetration depth of nerve tissue plotted with different frequencies. A one dimensional FDTD algorithm has been built, some simulations for electromagnetic wave through the nerve tissue is made. Results show that electromagnetic fields penetrate the life tissues and attenuate fast to reach zero at large time steps. SAR show maximum at the first boundary of tissue and becomes less value by using high frequency. Also, the result appear that penetration depth and relative permittivity decreased by increasing frequency.
