Fig. 1. (Top row) Theoretically generated 2D intensity source profiles of ABIBs derived from Eq. (7). (Middle row) Numerically reconstructed 2D intensity source profiles of ABIBs derived from Eq. (8). (Bottom row) Comparison of the corresponding 1D cross-sections of the ABIB source profiles obtained analytically as solid curves and numerically as dashed curves. The correlation parameter is set to 0.1 (left), 0.3 (middle), and 0.5 (right).

Fig. 2. Schematics of beam propagation through atmospheric turbulence. RPS₁–RPS_N represent the first and last phase screens and N denotes the number of phase screens employed in the simulations.

Fig. 3. Average intensity distributions of the ABIB (top panels) and the coherent Airy beam (bottom panels) propagating in a stretch of the weakly turbulent atmosphere over the thickness set to 0 (left), 1200 m (middle), and 2000 m (right). The structure constant is chosen as C_n² = 1 × 10⁻¹⁷ m^−2/3.

Fig. 4. Average intensity distributions of the ABIB (top panels) and the coherent Airy beam (bottom panels) propagating in the strongly turbulent atmosphere over the propagation distance set to 0 (left), 150 m (middle), and 300 m (right). The structure constant is chosen as C_n² = 1 × 10⁻¹³ m^−2/3.
