Field decomposition in compressible magnetoplasmas by a perturbation technique

The paper presents a method for the determination of the electromagnetic and pressure fields produced by a given distribution of source currents in a lossy, anisotropic, compressible plasma. With appropriate series expansions of the permittivity and compressivity tensors, a perturbation approach is used to decompose the coupled fields into partial fields which satisfy a family of recursive equations containing no tensor operators. The recursive equations are uncoupled, nonhomogeneous Helmholtz equations, similar to those governing an isotropic and compressible medium. The effective source-current density for the nth-order partial fields depends upon the interaction of the n ¿ 1 lower-order partial fields with the externally applied magnetic field.
