Abstract
It is shown for the first time, to our knowledge, that when a plane wave illuminates a certain type of bicomponent optical system, consisting of two plane screens with circular apertures on a given optical axis, a multifocal diffractive focusing effect can appear. Here the diffraction picture in the focal planes represents the circular nonlocal bands of the Fresnel zones with a bright narrow peak at the center, whose intensity can exceed by 6–10 times the value of the incident-wave intensity. The detected optical effect is observed across a wide range of wavelengths, λ = 0.4–103 μm, and ratios of the aperture diameters d1 ≥ 2d2 = 25–1000λ, and it is also insensitive to changes in the medium of the wave propagation. For the large diameters of input holes, d1 = 2d2 > 100λ, or for wavelengths in the radio-frequency region of the spectrum, the bicomponent diffraction system acts as a long-focus lens with a high-intensity Gaussian distribution of radiation, at times exceeding the initial intensity, persisting at large distances (z = 1–100 cm) from the diffraction system.
