We study the effect on the reflected intensity of morphology-dependent resonances of an object buried beneath either a flat or a randomly rough surface. Rigorous two-dimensional numerical calculations of electromagnetic scattering are put forward to explain the relationship between the size of the object and the consequent scattered intensity by the system–object interface. Different cases have been investigated to clarify the dependence of the results on the interface profile and permittivity, as well as on the width of the incident beam.
