Ionospheric modification and parametric instabilities

- J. A. Fejer
- Physics
- 1 February 1979

Thresholds and linear growth rates for stimulated Brillouin and Raman scattering and for the parametric decay instability are derived by using arguments of energy transfer. For this purpose an… Expand

On the stability of a plane vortex sheet with respect to three-dimensional disturbances

- J. A. Fejer, J. Miles
- Physics
- 1 March 1963

The previously established criterion for the stability of a vortex sheet with respect to two-dimensional disturbances in a compressible fluid is extended to three-dimensional disturbances, and it is… Expand
