Generation of diffraction-free petallike beams based on stationary phase principle
Results in Physics, 2022 Lately, a kind of so-called “combined half-integer Bessel-like beams,” in which their subfamilies include radial carpet, petallike, and ringlike vortex beams, has been generated using a radial periodic grating.

Two-dimension trapezoidal grating raytracing based on the scalar diffraction and scattering theory
AIP Advances, 2018 Diffraction grating is a fundamental optical element in spectral measurement or source monochromation. A newly designed grating named as two-dimension trapezoidal grating (TG), which not only has non-harmonic diffraction, non-background contaminations ...

Band-edge-induced Bragg diffraction in two-dimensional photonic crystals [PDF]
, 2006 Two-dimensional photonic crystals composed of two orthogonal volume diffraction gratings have been photogenerated in photopolymers. When the read beam is set at the Bragg angle, the diffraction efficiency of the transmission grating is strongly enhanced ...
