Resumen
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.

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. [--]
