Abstract
We study the effective nonlinear susceptibility tensor d(- 2 omega;omega,om
ega) for second-harmonic generation and chi for third-harmonic generation i
n a nonlinear composite medium. Simple expressions for these susceptibiliti
es in terms of the position-dependent nonlinear susceptibilities of the con
stituents and local field factors in a corresponding linear medium are used
to evaluate the nonlinear response. These expressions are useful starring
points to develop effective medium approximations. (C) 2000 Elsevier Scienc
