摘要

本文分析了超宽带(UWB)脉冲在人体内的反射和吸收两大传播特性。本文考虑了一种简化的多层非均匀人体组织模型。研究了超宽带脉冲在多层组织模型中传输的s参数和路径损耗。利用基于Cole-Cole模型的人体组织介电常数和电导率等与频率相关的三层(皮肤、脂肪和肌肉)电磁特性进行模拟。比吸收率(SAR)与内部电场和电导率直接相关，在1-5 GHz的宽频带范围内计算。

Propagation characteristics of ultra-wideband pulse in multilayered human chest tissue

In this paper two major propagation characteristics such as reflection and absorption of Ultra-wideband (UWB) pulse in a human body have been analysed. A simplified multi-layered non-homogenous model of human tissue is considered here. S-parameters and path loss due to transmission of UWB pulse in the multi-layered tissue model are evaluated. Frequency dependent Electromagnetic properties of three layers (skin, fat and muscle) such as permittivity and conductivity of human tissues based on Cole-Cole model are used for the simulations. Specific Absorption rate (SAR), which is directly related to the internal electric field and the conductivity, is computed at a wide band of frequency ranging between 1–5 GHz.
