An Analytical Solution of the Multiple Scattering from a Buried Medium Coated Conducting Sphere

“…nm (r, k) in Equations ( 8) and ( 9) can be shown in [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]:…”

“…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].…”

“…Some scholars have turned their attention to the problem of electromagnetic scattering characteristics of complex spherical targets after studying the scattering of a single-layer sphere by plane waves. 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.…”

“…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.…”

Scattering characteristics of dual Gaussian beams by a uniaxial anisotropic coated sphere

“…In 2018, Ahmed et al [17] investigated electromagnetic scattering from an orthorhombic dielectric-magnetic sphere with dielectric coatings using the T-matrix method. In 2021, Gao et al [18] derived an analytical solution for the electromagnetic scattering of a charged coated sphere based on Lorenz Mie theory, and analyzed its scattering characteristics. The results show that the surface potential and the radius ratio of the two layers have an impact on the extinction efficiency when the sphere's surface is charged.…”
