  • Belyi, VN; Forbes, A; Kazak, NS; Khilo, NA; Ropot, PI (Society of Photo-Optical Instrumentation Engineers (SPIE), 2009-08)
    A new type of Bessel-like optical beams, which is distinguished by the dependence on the cone angle from the longitudinal coordinate, is investigated. Such beams have the properties of Bessel beams (ring-spatial spatial ...
  • Belyi, VN; Kazak, NS; Khilo, NA; Forbes, A; Ropot, PI (Society of Photo-optical Instrumentation Engineers (SPIE), 2009-08)
    The spectrum of spatial frequencies (SFS) of Bessel beams properties emerging at their spatial localization is investigated. The case, when limiting aperture has a circular shape and a center at any distance from the optical ...
  • Belyi, VN; Kazak, NS; Khilo, NA; Forbes, A; Ropot, PI (Elsevier, 2011-11)
    In this paper the authors consider the angular spectrum of an apertured Bessel beam when the aperture is circular and shifted laterally with respect to the optical axis. Since the perturbation of the resulting angular ...
