Wave‐wave coupling in nonresonant unstable systems

Wave‐wave coupling in nonresonant unstable systems

The expansion of the dielectric function, employed in deriving the equations for wave‐wave coupling, often diverges if the wave‐particle interactions are nonresonant. This difficulty can be avoided by expanding about the complex eigenmodes of the linear system. This is illustrated for a cold beam‐pl...

Zusammenfassung:The expansion of the dielectric function, employed in deriving the equations for wave‐wave coupling, often diverges if the wave‐particle interactions are nonresonant. This difficulty can be avoided by expanding about the complex eigenmodes of the linear system. This is illustrated for a cold beam‐plasma system.
