Simulation for Frequency Response of Transmission of UWB Signal in a
Beating Heart
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.
