Abstract
A small metal sphere interacting with an incident electromagnetic wave will produce second-harmonic radiation in a quadrupolar mode. A hydrodynamical model for the electron gas is employed and a Green-function formalism is used to solve for the cross section for producing second-harmonic generation. Numerical results are obtained for aluminum and silver.Keywords
