This paper reports on numerical studies of the generation of second-harmonic radiation by a p-polarized electromagnetic wave incident on an inhomogeneous overdense plasma. Maximum second-harmonic emission coincides with maximum absorption of the fundamental wave. The importance for second-harmonic emission of electromagnetic structure resonances due to density plateaus near the critical layer is demonstrated.
