|dc.description.abstract||Body centric communication has been extensively studied in the past for a range of frequencies,
however the need to reduce the size of the devices makes nano-scale technologies
attractive for future applications. This opens up opportunities of applying
nano-devices made of the novel materials, like carbon nano tubes (CNT), graphene
and etc., which operate at THz frequencies and probably inside human bodies.
With a brief introduction of nano-communications and review of the state of the
art, three main contributions have been demonstrated in this thesis to characterise
nano-scale body-centric communication at THz band:
• A novel channel model has been studied. The path loss values obtained from
the simulation have been compared with an analytical model in order to verify
the feasibility of the numerical analysis. On the basis of the path loss model and
noise model, the channel capacity is also investigated.
• A 3-D stratified skin model is built to investigate the wave propagation from the
under-skin to skin surface and the influence of the rough interface between different
skin layers is investigated by introducing two detailed skin models with
different interfaces (i.e.,3-D sine function and 3-D sinc function). In addition, the
effects of the inclusion of the sweat duct is also analysed and the results show
great potential of the THz waves on sensing and communicating.
• Since the data of dielectric properties for biological materials at THz band are
quite scarce, in collaboration with the Blizard Institute, London, UK, different
human tissues such as skin, blood, muscle and etc. are planned to be measured
with the THz Time Domain Spectroscopy (THz-TDS) system at Queen Mary
University of London to enrich the database of electromagnetic parameters at
the band of interest. In this chapter, collagen, the main constitution of skin was
mainly studied. Meanwhile, the measured results are compared with the simulated
ones with a good agreement.
Finally, a plan for further research activities is presented, aiming at widening and
deepening the present understanding of the THz body-centric nano-communication
channel, thus providing a complete characterisation useful for the design of reliable
and efficient body centric nano-networks.
