摘要: A new approach to inhomogeneous layer synthesis is proposed that differs from the classical Fourier transform methods. This approach, based on wave-number discretization of continuous Q function, described together with relationship between smoothness layer’s refractive-index profile, complexity target reflectance specification, and total optical thickness layer. An iterative procedure introduced overcome inaccuracy connected approximate Q-function representation. Some control features phase are studied, numerical examples given.
