Nonlinear tunneling of electromagnetic wave through a plasma layer

Background and Objectives: The propagation of a strong plane electromagnetic wave from a vacuum through a limited plasma layer is considered, taking into account non-linearity under tunneling and transparency conditions. The temperature dependence is not taken into account. The non-linearity is taken into account phenomenologically as the dependence of the plasma frequency and collision frequency on the field averaged over the period squared.

Methods for Enhancing Emissive Ability of the Carbon Nanotubes

The analysis of papers devoted to study of the emission properties of the carbon nanotubes and to revealing ways for the control of these properties has been performed. Five main methods for enhancing emissive ability of the carbon nanotubes have been singled out.
