Abstract

This paper presents i) a model for ultra-wideband (UWB) wave propagation through a human thorax and ii) estimation via simulation, of transmission coefficient at various frequencies in the UWB range 1-10 GHz using CST Microwave Studio. This study clearly indicates that the variation of power transmission coefficient of UWB signal has a strong correlation to the instantaneous dimension of the heart in a cardiac cycle, a feature that can be exploited in detecting cardiac activity of human being in inaccessible conditions using radar based principles.
