We derive expressions for the effective nonlinear susceptibility tensors for both the second harmonic generation (SHG …) and induced third harmonic generation (THG) of nonlinear composite materials, in which nondilute coated particles with … first is that the core possesses a second order nonlinear susceptibility and the shell is linear and radially anisotropic …
