RT Journal Article T1 Fresnel diffraction by deterministic fractal gratings: An experimental study A1 Rodrigo Martín-Romo, José Augusto A1 Rodríguez Merlo, Daniel A1 Calvo Padilla, María Luisa A1 Alieva Krasheninnikova, Tatiana AB Experimental results are presented for light diffraction under the Fresnel regime by two types of fractal gratings: triadic Cantor bars and Vicsek fractals. It is shown that the evolution of the diffraction patterns in the Fresnel regions reveals the hierarchical structure of deterministic fractal gratings.
