Abstract
Using the input impedance method, the basic characteristics of electromagnetic wave reflection in multilayered media are theoretically calculated. Numerical modeling and physical simulation helped estimate amplitudes of GPR waves reflected from layers in a multilayered medium, and the reflection coefficients were determined for every layer of different thickness.
