“…The methodology was first proposed by Georgian mathematician Viktor Kupradze and then, Revaz Zaridze utilized the approach in electromagnetic scattering [16,17]. Since then, the method is not only been used for the direct problem but also, for 2D and 3D inverse problems that are solved and validated by the other methods [18,19]. In [18], the characterization of the electrical properties of the dielectric objects is investigated by employing the method of auxiliary sources.…”

In this article, the periodic pulse diffraction from the circular dielectric object radiated by the horn antenna is investigated and experimental verification is provided. The pulse spectrum with Hamming weight function (Hamming window) form occupies the frequency band of 38 – 52 GHz. The problem is solved using the Method of Auxiliary Sources, and the results of the computer simulation are obtained. The fundamental advantage of the method is to eliminate the singularity problem during the solution of the integral equation obtained by boundary conditions on each scatterer. The comparison is done with the experimental data, which shows good agreement between the simulation outcomes and the experimental ones. The correctness of the determination of the electric size of the object by the analysis of the scattered pulse echo serves as the verification of the approach. The outcomes reveal that less than a 3% deviation is observed between numerical and experimental analysis.

“…The importance of the subject is to obtain such information by noninvasive approaches. In general, electromagnetic waves are employed since the waves can propagate through the media [4]. The reflection and scattering of the electromagnetic waves from discontinuities and edges lead to obtaining information from the region of interest.…”

“…There are many different analytical and numerical approaches regarding the inverse problem. However, in the present study, the Method of Auxiliary Sources is employed to investigate the determination of an object buried underground [4,[8][9][10]. A two-dimensional ring was investigated previously in [4], and the comparison was made with analytical outcomes.…”

This study provides an alternative and straightforward approach to determining buried dielectric objects underground by employing the method of auxiliary sources. In the direct scattering problem, the Brewster angle is determined, and then the electromagnetic properties of the ground are determined. Later, the scattered field above the ground due to the buried object is evaluated. The localization of the buried object is obtained by the continuity of the field components while solving the inverse problem. The numerical experiments are done, and outcomes of the numerical experiments are compared with a commercial full-wave computational electromagnetic software. The outcomes reveal less than 1% deviation between the proposed approach and the commercial tool.
