  5. The observations of the Fast satellite [Ergun et al., GRL, 1998].

  6. Characteristics: 1. The structures have a positive potential signature. 2. The parallel slicing of parallel electric field has bipolar structures. 4. The parallel slicing of perpendicular electric field has unipolar structure. 5. Debye-scale size in the parallel direction.

  7. The stacked profiles of the electric fields from 1D PIC simulations.

  8. The electric field and phase-space diagram of electrons from 1D PIC simulations.
