    Evaluation of the Brillouin precursor performance for ultra wide band intra-body technologies
    (Taylor&Francis, 2013) Falcone Lanas, Francisco; Dawood, Muhammad; Aguirre Gallego, Erik; Azpilicueta Fernández de las Heras, Leyre; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this letter, we describe the formation and the evolution of Brillouin precursorfields through human tissues by using a frequency-domain analysis technique and amulti-pole Cole–Cole model to characterize the dielectric properties of the humanbody tissues, in a frequency band designated by the FCC for ultra wide bandmedical applications, which extends from 0.5 to 20 GHz. A 3D representation of thehuman body model has been implemented by employing a discretized mesh ofcuboids with a resolution of 8 mm3in which the frequency dispersive materialparameters for different tissues have been considered. The dispersive propagation isanalyzed for the purposes of radar imaging and intra-body communications. The per-formance of a classical rectangular pulse, a Brillouin pulse and a medium-matchedwaveform is described. The results show the potential application of this type ofcommunication scheme in order to improve the achievable measurement range andprovide better signal to noise ratios.
