Initial Work

The study of plasma instabilities described by the inclusion of a finite conductivity in the hydromagnetic equations has aroused considerable interest since the initial work of Furth, Killeen and Rosenbluth for a two-dimensional geometry. In particular, the so-called ‘tearing’ mode, which has been observed in laboratory plasmas, has been suggested as a possible source of energy for solar flares.

Numerical Calculation Method

As the classic analytical methods cannot calculate the electromagnetic scattering characteristics at Low Grazing Angle (LGA), a novel numerical method is presented by utilizing the Radar Cross Section (RCS) of the low grazing two-dimensional PM sea spectrum based on the triangles-based Physical Optics (PO) method in this paper. The calculated RCS is compared with the numerical calculation method of different targets and frequencies of incident wave. The results show that PO method is more accurate, especially under LGA condition, and it has a better agreement with the results calculated by commercial software FEKO.

We consider the problem of neutral inclusions for two-dimensional conductivity and anti-plane elasticity. The neutral inclusion, when inserted in a matrix having a uniform field, does not disturb the field outside the inclusion. The inclusion consists of a core and a shell. We show that if the inclusion is neutral to two linearly independent fields, then the core and the shell are confocal ellipses.
