Obliquely propagating monotonic double layers in a magnetized plasma

A theoretical investigation is carried out for understanding the properties of obliquely propagating monotonic double layers in a magneto-plasma. By using Sagdeev's pseudopotential method, we have found an obliquely propagating double layer solution and a relation between the amplitude, the inverse scale length and the obliqueness effects. Furthermore. we show that the monotonic double layers are nonlinear extensions of the solitary holes having negative trapping parameter in magnetized plasma.
