In an analysis of the second-order temporal echo in a semi-infinite isotropic plasma on the basis of the model of specular reflection of electrons on the plasma boundary, an equation is derived for the nonlinear echo signal. This equation has two terms: a first term corresponding to volume waves (it is the expression for the echo field in an infinite plasma) and a second term due to the boundary. The repeated excitation of two highly damped shortwave oscillations in a plasma is accompanied by the appearance of longwave echo oscillations, which exist near the plasma boundary and whose nature is governed by the surface-wave dispersion.
