The spatial echo in a plasma slab is studied for the case in which there is a magnetic field normal to the slab boundaries. The mean free path of the plasma particles is assumed much larger than the slab thickness, and the carrier reflection of the slab boundaries is assumed specular. The repeated reflection of plasma particles from the slab boundaries and the repeated modulation of their distribution function have the consequence that the echo signal is much stronger than in the case of an unbounded or semiinfinite plasma, provided that certain relations are satisfied among the frequencies of the sources exciting the plasma and the gyrofrequencies. This resonance was first studied for the case of longitudinal waves by V. F. Dryakhlushin and Yu. A. Romanov )Fiz. Plasmy 2, 810 (1976) (Sov. J. Plasma Phys. 2, 451 (1976))). The particular nature of the conditions for an echo resonance in a magnetized plasma slab depends on the polarization of the sources perturbing the plasma.
