Nonlinear development of the negativehyphen;mass instability and its effect on intense microwave generation

摘要

The nonlinear development of the negativehyphen;mass instability is investigated for a thinElayer (Dgr;Lt;R0) located inside a cylindrical waveguide. A quasilinear analysis shows that the instability saturates by the development of an energy spread and a corresponding increase in thickness Dgr; of theElayer. The efficiency of microwave generation by this instability is also calculated.
