“…region and allowed to diffuse into the target region. In the past, these have been widely used in developing a fundamental understanding on the large number of physical phenomenon namely, collisionless electrostatic shock [1], ion beams, ion waves [2,4], ion-acoustic instability [3], linear and nonlinear electrostatic waves [2], plasma waves [5,6], electron plasma waves [7,8] ion-acoustic soliton [9,10], potential relaxation instability [11], double layers [12][13][14][15], etc by realizing minor modifications in its geometry and usage.…”
