Fat-IntraBody Communication at 5.8 GHz: Verification of Dynamic Body Movement Effects Using Computer Simulation and Experiments

This paper presents numerical modeling and experimental validation of the signal path loss at 5.8 GHz Industrial, Scientific, Medical (ISM) band, performed in context fat-intrabody communication (fat-IBC), a novel intrabody platform using body-omnipresent fat tissue as key wave-guiding medium. Such work extends our previous works 2.0 2.4 characterization its performance other useful frequency range. In addition, this also includes studies both static dynamic human body movements. order to provide with more comprehensive frequency, focuses on investigating different configurations thickness, antenna polarizations, locations channel. We bring realism by excised tissues from porcine cadaver their muscle have electromagnetic characteristics similar those respect current state-of-art artificial phantom models. Moreover, for favorable excitation reception fat-IBC model, we used topology optimized waveguide probes. These probes an almost flat response range 3.2 7.1 which is higher than improve evaluation model. discuss various aspects real-world scenarios examining models, particularly homogeneous multilayered skin, fat, tissue. To study effect movements, examine impact misalignment, space wave polarization, between implanted nodes. show particular that use techniques can be extended up broadband channel GHz.
