Development of 3D human tissues phantoms for analysis of frequency dispersion and human body interaction at 60GHz

Dispersive propagation could result of particular importance in the case of technologies involving human tissues. High-resolution systems as employed in medical imaging require the use of ultra wide band waveforms and for such pulses the medium is inherently dispersive. This will unavoidably lead the Brillouin or Sommerfield precursors to emerge even if they are not explicitly visible. However its analysis is not considered in body-centric radio channel characterization and models. For intra-body communications, the form and shape of the information-bearing transmitted signal is also an important factor to consider (Alejos, et al., JEMWA, 27(17), 2213–2220, 2013). Since the transmitted signal influences the formation and performance of the resulting precursor, we can conclude that a medium-matched signal can lead to optimal performance by combining the benefits of the precursor formation (larger amplitude) with minor impairments (lesser time duration broadening).
