本文提出了一种评估如何诺顿表面波可以用来分析模型的无线体域网的身体传播。在简要回顾Norton表面波理论的基础上，统一了由Sommerfeld定义的陆地传播的一般问题，并考虑到Norton和班尼斯特的进一步扩展，从而激发了对体传播的评价。索末菲的数值距离的讨论揭示了有用的属性，以评估特定的配置，以激发诺顿表面波在特定的身体上的情况下的能力。基于此，可以导出用于体上传播链路的天线设计准则。所有的研究都是在0.4 GHz到60 GHz的频率范围内对人体肌肉、皮肤和脂肪组织进行的。由平面均匀地面组成的简化模型与现实的非均匀人体模型的比较表明，电场强度沿身体路径沿着衰减的结果良好。
This paper presents an evaluation on how Norton surface waves can be used to analytically model the on-body propagation in wireless body area networks. Based on a brief review of the Norton surface wave theory, the general problem as defined for terrestrial propagation by Sommerfeld, is unified taking into account the further extensions by Norton and Bannister which motivates its evaluation for on-body propagations. A discussion of Sommerfeld's numerical distance reveals useful properties to evaluate the capability of a certain configuration to excite Norton surface waves in specific on-body scenarios. Based thereon antenna design guidelines for on-body propagation links can be derived. All investigations are carried out for human muscle, skin, and fat tissues in the frequency range from 0.4 GHz to 60 GHz. A comparison of the simplified model consisting of a planar homogeneous ground to a realistic inhomogeneous human body model shows good results for the attenuation of the electric field strength along the on-body path.
