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
