Numerical modelling of electromagnetic wave interaction with heterogeneous biological structure

The paper presents a numerical modeling of electromagnetic wave interaction with planar layered structure through reflection and transmission coefficient at boundaries of two biological tissues. Numerical calculation both reflection and transmission coefficients at boundaries is investigated with respect to the multiple reflections of planar electromagnetic wave at boundaries and with the respect to the transmission of reflected wave between two layers represented by fat and muscle with known dielectric properties. In our paper we presented the frequency dependence of reflection and transmission coefficient over the microwave frequency range from 1 GHz to 30 GHz and also the influence of fat layer thickness at investigated coefficients
