Abstract :
An in-body path loss model in homogeneous human tissues is proposed based on 3D electromagnetic simulations and validated with measurements. Simulations are further extended for different relative permittivity and conductivity combinations spanning a range of human tissues at 2.45GHz, and the influence of the dielectric properties on path loss is investigated and modeled. Finally, path loss in homogeneous medium is compared with the path loss in a heterogeneous human phantom.
