Demonstration of 12 nm resolution Fresnel zone plate lens based soft x-ray microscopy.
To extend soft x-ray microscopy to a resolution of order 10 nm or better, we developed a new nanofabrication process for Fresnel zone plate lenses. The new process, based on the double patterning technique, has enabled us to fabricate high quality gold zone plates with 12 nm outer zones. Testing of the zone plate with the full-field transmission x-ray microscope, XM-1, in Berkeley, showed that ...
متن کاملthe fresnel zone plate antenna as an electromagnetic field focusing element.
fresnel zone plate antenna (fzpa) was considered as a recieving antenna. an expression of electric field on axis of antenna produced by an incidente plane wave was found . the expression was used for calculation of gain, efficiency and optimum phase correcting function. several fzpa are fabricated and tested. experimental and theoretical results were compared and it was shown that there was a g...

15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولThe Advantages of Dye-Doped Liquid Crystals in Constructing a Fresnel Zone Plate Lens
A Fresnel zone plate lens can be constructed using a dye-doped liquid crystal filled cell and photo-induced alignment techniques. Light passing through a Fresnel zone patterned photo-mask causes the dye-doped liquid crystal to align in such a way to produce odd and even zones on the lens. Diffraction of incident light through the odd and even zones of the lens allows the light to constructively...
