Modeling of In-Body Propagation Characterization for 2.5/3.5 GHz Implantable Devices Applications

Abstract:

To investigate the propagate channel for implantable devices deep inside of a human body to receiver on-body or outside body, a 3D electromagnetic model of human body which including 85 kinds of different human tissues and organs, based on CT and MRI slices data take from living human males, was built. The in-body channel path gain in different distance for 2.5/3.5 GHz biomedical implants was investigated using electromagnetic (EM) simulator and its numerical sta-tistical model was presented. EM simulation and numerical computational results show that the dis-tance dependent path gain for inside body can be modeled by a modificatory classical power law function with root-mean-square error (RMSE) of 2.6 and 3.9 for 2.5 GHz and 3.5 GHz, respectively
