abstract
Theory of second harmonic generation at a metal surface is developed, when surface plasmon-polaritons are resonantly excited by the incident electromagnetic field. For harmonic generation from small metallic spheres characterized by the dielectric function {lunate}1() + i{lunate}2(), the resonant enhancement of the second harmonic intensity is predicted to be of the order of ( {lunate}1 {lunate}2)4. The resonant enhancement is much smaller for the case of a metallic grating. 1982.
