“…The incident soliton is the dotted one and is taller than the reflected one. The smaller amplitude of the reflected soliton in comparison with the amplitude of the incident soliton is a similar result to that obtained in [9], [10], and [16]- [19]. When the solitons get reflected in an inhomogeneous plasma with two-temperature electrons, we observe that the reflected solitons get downshifted from their original line of propagation.…”

“…When the solitons get reflected in an inhomogeneous plasma with two-temperature electrons, we observe that the reflected solitons get downshifted from their original line of propagation. Such shift could not be explored in earlier investigations on soliton reflection [12]- [16], [38], [40], [41]. Fig.…”

“…Later, he, along with Nagasawa [15], studied the nonlinear reflection and refraction of the solitons from a metallic mesh electrode in a double-plasma (DP) device. It is generally observed that the amplitude of the reflected soliton is lesser than that of the incident soliton [9], [10], [16]- [19]. Apart from the inhomogeneity, the effect of two-temperature electrons has been studied on the soliton propagation and reflection.…”

This paper aims at studying the oblique reflection of solitons in an inhomogeneous plasma having finite-temperature ions and trapped electrons (two-temperature nonisothermal electrons). In order to study the soliton reflection, a coupled equation is derived based on modified Korteweg-deVries equations for the incident and reflected solitons, and then, it is solved along with the use of incident soliton solution. The expressions for the reflected soliton amplitude, width, and reflection coefficient are obtained and examined for different parameter regimes. The reflection coefficient, which is the ratio of reflected and incident soliton amplitudes, is found to be independent of the ion and electron temperatures. It infers that both the amplitudes change in the same proportion with the ion and electron temperatures. It is observed that the soliton reflects with higher amplitude when the obliqueness is smaller. It is also seen that the reflected soliton undergoes a downshift in its original line of propagation. This downshift is further investigated in detail. The effect of the trapped electrons on the soliton reflection characteristics and on the downshift is also analyzed.

“…18,19 This reflection has been explained by a reexcitation mechanism. 20 In this mechanism, the incident wave is stripped of its electron component while the ion component passes through the grid. The reflection properties in a negative ion plasma are different from those in a two-component plasma.…”

Reflection of modified Korteweg–de Vries solitons from the sheath in front of a negatively biased metal disk is experimentally investigated in a negative ion plasma. Both rarefactive and compressive solitons are reflected and the polarity of the reflected solitons is the same as that of the incident solitons. The points of reflection for the rarefactive and compressive solitons are at different locations. As the magnitude of the negative bias potential that is applied to the reflector is increased, the two reflection points move away from the reflector. An interpretation in terms of the sheath characteristics is presented.
