Soliton reflection in a magnetized inhomogeneous warm plasma: effect of ionization

The reflection of nonlinear solitary waves isstudied in a plasma under the effect of an external magneticfield and constant ionization along with finite ion temperature.To investigate the reflection of solitary waves, relevantmodified Korteweg–deVries equations for the rightand left going waves are derived, and coupled at the pointof reflection for obtaining the expression of reflectioncoefficient. The solitary waves are found to shift after theirreflection. Variation of reflection coefficient and shift arestudied for different plasma parameters like ion temperature,ionization rate and wave propagation angle or theobliqueness of magnetic field.
