Abstract
Nonstationary absorption of the energy of a short electromagnetic-radiation pulse in a superdense semibounded plasma is considered. An approach is proposed for finding the electron distribution function, wherein the region of the skin layer (in the anomalous skin-effect regime) is described as a boundary condition for the distribution function over the entire plasma volume. A self-similar electron-distribution function is obtained and is used to analyze the dynamics of the electromagnetic-field absorption, of the heat transfer, and of the bremsstrahlung of the heated plasma.
