Orbitalt impulsmoment (bølge): Forskelle mellem versioner

En OAM kan også dannes ved at klippe i en reflektor og forskyldeforskyde dens forskellige reflektor "[[cirkeludsnit]]"., så de passer med den ønskede fase rundt fx fra -180...180 grader ved OAM= +1 eller -1.<ref>[http://iopscience.iop.org/article/10.1088/1367-2630/14/3/033001 Fabrizio Tamburini et al 2012 New J. Phys. 14 033001, iopscience.iop.org: Encoding many channels on the same frequency through radio vorticity: first experimental test] Citat: "...Moreover, our experimental findings demonstrate that the spatial phase signature was preserved even in the far-field region and for incoherent non-monochromatic wave beams. These results open up new perspectives not only for wireless communication but also for physics and astronomy, including the possible detection of Kerr black holes in the test general relativity [21]...A.4.
