Inverse-phase composite zone plate providing deeper focus than the normal diffraction-limited depth of X-ray microbeams
A novel type of zone plate (ZP), termed an inverse-phase composite ZP, is proposed to gain a deeper focus than the standard diffraction-limited depth of focus, with little reduction in spatial resolution. The structure is a combination of an inner ZP functioning as a conventional phase ZP and an out...
