ANALYTICAL STUDY ON THE RESONANT ABSORPTION OF LIGHT IN NON-UNIFORM PLASMA
光在等离子体中的共振吸收解析研究

The resonant absorption of light in cold plasma for linear density profile has been calculated analytically both for long and short scalelengths by calculating the reflectivity from the plasma and vaccum interface. The results in long scalelength case are in agreement with the well-known results but with a higher order in accuracy, and that in short scalelength case are consistent with numerical calculation.
