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.application/pdfeng© 2013 Taylor & FrancisBrillouin precursorFrequency dispersionPower extinctionUltra wide-bandinfo:eu-repo/semantics/article2024-01-12info:eu-repo/semantics/openAccess
