We report on a novel type of an aperiodic one-dimensional multilayered structure which can be used for terahertz radiation manipulations. The studied structure is formed by stacking together dielectric layers according to the Kolakoski self-generation scheme. Numerical simulations are carried out for different configurations of the structure to reveal the dependence of its optical characteristics on the generation stage, frequency, and the angle of wave incidence. The dependence of the number and width of omnidirectional bandgaps on the refractive indexes and the thicknesses of the dielectric materials is studied.
