Abstract

Human intestines are vital organs, which are often subjected to chronic issues. In particular, Crohn's disease is a bowel aliment resulting in inflammation along the lining of one's digestive tract. Moreover, such an inflammatory condition causes changes in the thickness of the intestines; and we posit induce changes in the dielectric properties detectable by radar. This detection hinges on the increase in fluid content in the afflicted area, which is described by effective medium approximations (EMA). In this paper, we consider one of the constitutive parameters (i.e. relative permittivity) of different human tissues and introduce a simple numerical, electromagnetic multilayer model. We observe how the increase in water content in one layer can be approximated to predict the effective permittivity of that layer. Moreover, we note trends in how such an accumulation can influence the total effective reflection coefficient of the multiple layers.
