This paper presents a study of subject-specific radio channels in wireless body area networks (WBANs). The simulation tool is based on a parallel finite-difference time-domain method (FDTD) and is well suited to model radio propagations around complex, inhomogeneous objects including human bodies in WBAN. It is found from our study that radio channel characteristics in WBAN are subject specific when...
In this paper a hybrid method for modelling on-body propagation channel has been presented. The original problem is split into two sub-domains: the antenna is analyzed with the commercial software CST, while the human body is handled with the FDTD; the equivalence principle is used as interface between the two sub-domains. The method has been applied to analyze a typical on-body scenario at the unlicensed...
