<p>The present inventions provide for bending the beams, their focusing, transforming a divergent radiation into a quasi-parallel one, and vice versa, its filtering and monochromatization. There are also attained reduced radiation transfer losses, extended range of energies used, and higher radiation concentration. A possibility is provided for use of larger radiation sources without decreasing the proportion of the captured particles, as well as for controlling the radiation spectrum. With this purpose in view, provision is made in the proposed method, apart from multiple reflection of particles upon interaction with different-density alternating media, also for diffuse and potential scattering or interference of particles that diffract on multilayer structures applied to reflecting surfaces. In a device carrying the proposed method into effect the aforementioned surfaces are coated with layers differing in electromagnetic properties. The optical system of the device appears principally as a set of miniature lenses or hemilenses 28, built up of a plurality of capillaries or polycapillaries, the walls of whose channels 24 are provided with an appropriate coating 22. No use of any support structures for forming the profiles of the optical system is required. <IMAGE></p> |
