(1)　Dispersion Theory of Liquids Containing Optically Linear
　　　　and Nonlinear Maxwell Garnett Nanoparticles Optical Review,Vol.8,No.1,pp.9-17,2001-2

Kramers-Kronig relations and sum rules for effective linear permittivity of the Maxwell Garnett liquidnanosphere system were obtained using complex analysis and general expression of the effective permittivity. When reflectance from optically liner and nonlinear Maxwell Garnett nanoparticles was calculated it was observed that the reflectance, in the case of ttenuated total reflection, depends on the fill fraction of the nanospheres and their nonlinear susceptibility. According to simulations a good sensitivity of the nonlinear contribution on the reflectance can be obtained by using a probe wavelength corresponding to the resonance frequency of the nanosphere system. In Kretchmann’s configuration it was observed that the surface-plasmon-resonance angle depends on the fill fraction and on the intensity of the incident light. By using reflectance, it is possible to detect optically nonlinear nanospheres in liquids.
