Abstract
We considered the influence of multilayer structure parameters which are the index contrast, the period's number and the reference wavelength on the transmission spectrum of a deformed structure. Deformation was introduced by applying the power law y = x(k+1). We revealed that the higher optical index contrast enhance the deformation effect on transmission properties of the structure at normal incidence. This work is a detailed study of the effect of the deformation introduced in the multilayer stack according to the mentioned law.
