In this paper, the scattering of a Bessel beam by PEC and dielectric circular cylindrical scatterers is analyzed and discussed. In particular, it is shown that the scattering by nondiffractive beams is in general spatially localized in both cases, due to the remarkable focused beam features: the wave-front inside the main beam is locally planar, and the sidelobes are not so high, due to the abrupt amplitude shaping of the zeroth order Bessel distribution. The inherent localized scattering process paves the way to novel applications in microwave imaging and ground penetrating radar design.

Abstract

In this paper, the scattering of a Bessel beam by PEC and dielectric circular cylindrical scatterers is analyzed and discussed. In particular, it is shown that the scattering by nondiffractive beams is in general spatially localized in both cases, due to the remarkable focused beam features: the wave-front inside the main beam is locally planar, and the sidelobes are not so high, due to the abrupt amplitude shaping of the zeroth order Bessel distribution. The inherent localized scattering process paves the way to novel applications in microwave imaging and ground penetrating radar design.
