| 中文摘要 | a model for refractive index of stratified dielectric substrate was put forward according to theories of inhomogeneous coatings. the substrate was divided into surface layer, subsurface layer and bulk layer along the normal direction of its surface. both the surface layer (separated into n-1 sublayers of uniform thickness) and subsurface layer (separated into n-2 sublayers of uniform thickness), whose refractive indices have different statistical distributions, are equivalent to inhomogeneous coatings, respectively. and theoretical deduction was carried out by employing characteristic matrix method of optical coatings. an example of mathematical calculation for optical properties of dielectric coatings had been presented. the computing results indicate that substrate subsurface defects can bring about additional bulk scattering and change propagation characteristic in thin film and substrate. therefore, reflectance, reflective phase shift and phase difference of an assembly of coatings and substrate deviate from ideal conditions. the model will provide some beneficial theory directions for improving optical properties of dielectric coatings via substrate surface modification.
