“…It was shown by Bassanini [1974] that this procedure yields observable second-harmonic fields in the case of this problem; for a class of related problems, already considered in the Italian literature, see De Socio [1966,1968,1973] and Bassanini [1972]. Although part of the material has already been covered by Bassanini [1974], for the readers' convenience the analytical developments will be reported in full.

The problem of cross-modulation of the electromagnetic waves generated by two oscillating electric dipoles placed in the center of a spherical cavity surrounded by a nonlinear plasma is considered. One of the dipoles is amplitude-modulated with low (acoustic) frequency, and the plasma is assumed slightly ionized, rarefied, and cold. Second-harmonic generation is investigated by means of a perturbative technique in the frame of the "quasi-hydrodynamic" approach, assuming a nonzero electron collision frequency. Numerical results for the field modulated upon the sum of the frequencies of the two dipoles are given, in correspondence to values of the parameters of relevance for radio wave propagation in the ionosphere, and a nonlinear effect of resonance is emphasized.
