Medientyp: E-Artikel Titel: Multiple‐grating microwave volume holograms based on printed artificial dielectrics: Analysis and measurement Beteiligte: Zhu, Wenhao; McNamara, Derek A.; Shaker, Jafar Erschienen: Wiley, 2006 Erschienen in: Microwave and Optical Technology Letters Sprache: Englisch DOI: 10.1002/mop.21886 ISSN: 0895-2477; 1098-2760 Schlagwörter: Electrical and Electronic Engineering ; Condensed Matter Physics ; Atomic and Molecular Physics, and Optics ; Electronic, Optical and Magnetic Materials Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>A multiple‐grating artificial microwave volume hologram (AMVH) is presented, which is designed based on the idea of multiply‐exposed optical holograms and is realized using printed artificial dielectric technique. It consists of a 3D conducting disk array formed by cascading a finite number of planar disk lattices and has its disk size varying in both the transverse (<jats:italic>x</jats:italic>) and normal (<jats:italic>z</jats:italic>) directions to simulate an effective 2‐D holographic grating. The reconstructed beams from such a multiplex AMVH are analyzed and a low cross‐talk between gratings is obtained. Comparison with the measured results on the fabricated multiplex AMVH prototype has confirmed the design and simulation. © 2006 Wiley Periodicals, Inc.
