For absorbing coating materials the tasks of attainment of zero reflectivity and optimum transmittance (OT) are not equivalent. On the other hand, for some problems of the communication optics often arises the necessity to achieve OT of already prepared or engineering sample consisting of finite interference-free substrate of the refractive index s overlayered by a film with the preset refractive index t and phase thickness y.
