С. 228-231Abstract: Theoretical modeling of a Fresnel flat reflector for focusing radiation in the point near the reflector is discussed in this paper. It shows that the reflector calculated for one frequency and one focus position can also be used for other frequencies, but a focusing point should be shifted along a focusing line. Fresnel reflector can be used for a space-frequency filtration in a wide frequency range.
