The mathematical simulations based on the transfer function of the waveguide intra-body communication

The mathematical simulations based on the proposed transfer function of the waveguide intra-body communication (IBC) have been introduced in this paper. Firstly, a waveguide IBC circuit model was developed and the corresponding parameters were discussed. Secondly, the transfer function of the waveguide IBC was derived and proposed. Finally, the signal attenuation characteristics of the waveguide IBC were measured along the different signal transmission paths of the actual human bodies, while the corresponding mathematical simulations based on the proposed transfer function were carried out. Our investigation shows that the mathematical simulation results coincide with the measurement results over the frequency range from 100kHz to 5MHz, which indicates that the proposed transfer function offers the significant advantages in the theoretical analysis and the application of the waveguide intra-body communication.
