【Abstract】 A new analytical technique for obtaining a complete set of reflection, absorption and transmission coefficients for a stratified plasma slab is presented and named as scattering matrix method (SMM). The plasma model for the study is cold, steady_state, nonuniform, collisional and magnetized. The nonuniform plasma slab is modeled by a series of subslabs. Each subslab has a fixed electron density. The overall density profile across the whole slab follows a practical distribution function. The limit result is consistent with that given in literature. The reflective characteristics as a function of nonuniform plasma parameters as well as the thickness of slab for a parabolic density profile are investigated.更多还原
