    Acoustic Bessel-like beam formation by an axisymmetric grating 
    Jimenez, Noe; Romero García, Vicente; Picó Vila, Rubén; Cebrecos Ruiz, Alejandro; Sánchez Morcillo, Víctor José; García-Raffi, L. M.; Sánchez Pérez, Juan Vicente; Staliünas, Kestutis (European Physical Society, 2014-04)
    We report Bessel-like beam formation of acoustic waves by means of an axisymmetric grating of rigid tori. The results show that the generated beam pattern is similar to that of Bessel beams, characterized by elongated ...

    Formation of high-order acoustic Bessel beams by spiral diffraction gratings 
    Jimenez, Noe; Picó Vila, Rubén; Sánchez Morcillo, Víctor José; Romero García, Vicente; García-Raffi, L. M.; Staliünas, Kestutis (American Physical Society, 2016-11-23)
    The formation of high-order Bessel beams by a passive acoustic device consisting of an Archimedes' spiral diffraction grating is theoretically, numerically, and experimentally reported in this paper. These beams are ...
