EM Pulse Scattering Front Echo Reduction for the Dielectric Elliptical Cylinder Located inside Dielectric Media

This article presents a novel numerical approach to reduce scattering echoes in the front region of dielectric objects with the method of auxiliary sources. The method involves using a Gaussian radio pulse covering the 6–12 GHz frequency range. The approach involves optimizing the dimensions and dielectric permittivity of an elliptical cylinder in order to make it invisible, thus eliminating the need for metamaterial cloaking. The proposed approach has been validated by comparing the results of numerical experiments obtained during pulse echo observations with the FDTD and MoM numerical methods. The proposed method is a highly efficient and practical approach for scattering problems, such as scattering echo reduction, offering comparable results to FDTD and MoM methods with significantly reduced computational requirements.
