ABSTRACT

Plasma echo theory is revisited and reviewed to apply it to a semi-bounded plasma. Spatial echoes in a semibounded plasma are investigated by calculating the electric field produced by external charges and satisfying the boundary conditions at the interface. We show that echoes can occur at various spots. The diversity of echo occurrence spots is due to the boundary terms.
