This report offers a study of iron status in moist zones using a 1.6 GHz Ground Penetrating Radar (GPR). The latter is a geophysical prospecting tool that analyzes the propagation, refraction, and reflection of high-frequency electromagnetic (EM) waves (from 300 MHz to 2.3 GHz). To replicate GPR signals, we used the GPRMAX program, which allowed us to model the soil's electrical and magnetic properties as well as the GPR itself. Several models were created to replicate various geological situations. The simulation began with a rectangular block as the starting model. The first and second models are basic profiles that illustrate the propagation of an EM wave. The third model is used to investigate the propagation of EM waves (reflected waves) in dry and wet concrete in order to demonstrate the influence of moisture on EM waves. To simulate different properties of a dielectric medium, a set of models was built. We simulated several different physical media using a finite difference time domain (FDTD) approach, which is the method on which the scientific calculation code of the GPRMAX simulation program is based. When a radar signal propagates through an environment, the presence of hyperbolas indicates the presence of buried objects.
