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 UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000578354 ER -
