“…According to our investigation, most of the object scattering characteristics of vortex waves are concentrated in the optical band. In particular, some results are obtained by using the wave function expansion method for microparticle spherical objects [13][14][15][16][17]. In [13], the scattering of light beam with OAM is studied by the Mie scattering theory.…”

Based on the excellent and broad prospect of the vortex beams in military application, it is necessary to evaluate the scattering characteristics of classical Bessel beam upon a perfect electrical conductor (PEC) blunt cone model of aircraft structure. First, a Bessel beam is expanded by a series of plane wave spectra. Then, combining the physical optics (PO) method, the scattered field of the object fitted by facet elements can be calculated. The amplitude, phase, and orbital angular momentum (OAM) spectra of scattered field for different object attitudes are discussed in detail. The results show that the backward scattering still retains good OAM characteristics, and which are distorted with the increase of oblique angle. Besides, the backscattering radar cross section (BRCS) of aircraft are also calculated and analyzed, and the scattering results of degenerated zero-order Bessel beam and plane wave are compared to verify the correctness of the proposed theory. Compared with plane waves, object scattering of vortex beams provides a new degree of freedom, providing more information for object detection.INDEX TERMS Orbital angular momentum (OAM), Physical optics (PO), Plane wave spectra, Aircraft, Backscattering radar cross section (BRCS).

“…The study of isotropic spheres is inevitably associated with the classical Lorenz-Mie theory, also known as Mie scattering theory, which was proposed by Lorenz in 1898 and later refined by Mie in 1908 on the basis of a separation method in a spherical coordinate [1]. Since then, based on the Lorenz-Mie theory, some works have been published [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In [2], the radar cross section of a spherical target is discussed, and the theory that the radar cross section of an electrically large spherical target is twice the cross section of the sphere itself is explained in [3].…”

“…The scattering characteristics of uniformly charged coated spheres were analyzed in [6], and the charges on the inner core and outer shell were numerically calculated, respectively, when the surface is charged, and the extinction efficiency is affected by the radius ratio of the two layers and the surface potential. The problem of electromagnetic scattering of multilayered spheres is discussed after studying the electromagnetic scattering of single and coated spheres in [7], the study of scattering by two PEC spheres in terms of translation addition theorem is derived in [8], and in [9], the generalized Lorenz-Mie theory for laser-beam scattering by a perfect electromagnetic conductor (PEMC) sphere is derived and some characterization of laser scattering by a PEMC sphere is given in detail. In addition to the above studies, the problem of spherical electromagnetic scattering in free space is also discussed in [10,11].…”

“…The research of electromagnetic scattering from buried spheres is more complex to analyze than that by spheres in free space [1][2][3][4][5][6][7][8][9][10][11], but good progress has still been made [12][13][14][15][16][17][18] since electromagnetic scattering from buried objects can be used in the area of the detection of tunnels, pipes and mines, geophysical prospection, microwave remote sensing, medical diagnosis (skin tumor detection), etc. In [12], a general full-wave analytical solution is given to solve the problem of electromagnetic scattering by a buried dielectric or metallic sphere.…”

Based on the image method and addition theorem of spherical vector wave functions, an analytical solution of the multiple scattering by a buried medium-coated conducting sphere is proposed in this paper. An iterative process to obtain the scattered electromagnetic field is discussed on the basis of the continuous boundary condition in the plane boundary, the medium inner and the outer surface of a coated conducting sphere, respectively. Applying an image method and the addition theorem of spherical vector wave functions, the scattering electromagnetic fields by the plane in a local coordinate system can be transformed into the globe coordinate, and they can be regarded as the next incident electromagnetic fields to the buried medium-coated conducting sphere. This process does not end until the scattering electrical field on the plane boundary is accurate enough. Numerical results are given and compared with commercial software FEKO, they coincide enough; the calculation times of the present method are very short compared to those of the software FEKO, and some discussion is given at the end of this paper.
