    Description: The analytical expressions of electric fields inside and outside a magnetized cold plasma sphere are presented by reforming the spherical electromagnetic parameter based on the scales transformation of electromagnetic theory. The obtained results are in good agreement with that in literatures. The angle between the direction of inside field and that of outside field is derived. In S wave band, numerical calculations of effects induced on the inner field by parameters are established. Simulations show that the angle between incident field and the outside magnetic field influences the inner field remarkably. The inner field will decrease as the electron density increasing, however, this density has a great affect on the inner field's direction. The magnitude of the inner field is proportional to the incident wave's frequency. Keywords: Magnetized Cold Plasma, Scales Transformation, Electric Field

    Description: The transformation of parameter tensors for anisotropic medium in different coordinate systems is derived. The electric field for a magnetized cold plasma sphere and the general expression of scattering field from anisotropic target are obtained. The functional relations of differential scattering cross section and the RCS for the magnetized plasma sphere are presented. Simulation results are in agree with that in the literatures, which shows the method used and results obtained are correct and the results provide a theoretical base for anisotropic target identification etc. Keywords: Anisotropy, Scattering, Plasma

    Description: The backscatter properties of millimeter wave radar in sand and dust storms have been addressed. An expression for signal attenuation of millimeter wave radar is derived in terms of visibility and frequency. The results show that the values calculated by the proposed model are in good agreement...

    Description: The reflection and transmission of an incident Gaussian beam by a uniaxial anisotropic slab are investigated, by expanding the incident Gaussian beam, reflected beam, internal beam as well as transmitted beam in terms of cylindrical vector wave functions. The unknown expansion coefficients are determined by virtue of the boundary conditions. For a localized beam model, numerical results are provided for the normalized field intensity distributions, and the propagation characteristics are discussed concisely.

    Description: Based on the scales theory of electromagnetic field, we first introduce a new coordinates system, named scales coordinates system according to the elements of the dielectric tensor of the anisotropic medium. In the scales coordinates system, the anisotropic medium is changed to isotropic material, using the expression of the potential of an electric charge in presence of the isotropic medium and the scales invariants, the electric potential of a charge in the anisotropic medium is obtained. Then the electric potential of an electric dipole with a general direction are obtained by using the obtained potential formula in the anisotropic material to two electric charges with the opposite symbol and the method of Taylor's series expansion. By let the elements of dielectric tensor equal to each other, the anisotropic material will be an isotropic material, the obtained result completely equal to the those of a charge in free space in the available literatures, and the correctness of this obtained results are demonstrated. Finally some numerical results of the obtained electric potential of the electric dipole change with the anisotropic tensor are presented. The method used in this article will provide a new way of studying the electrostatic filed in the presence of anisotropic medium.
