Formation of high-order acoustic Bessel beams by spiral diffraction gratings
Jimenez, Noe; Pico Vila, Rubén; Sánchez Morcillo, Victor José; Romero García, Vicenç; Garcia Raffi, Luis Miguel; Staliunas, Kestutis (2016-11-23)
Article
Accés obertThe 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 ... -

Rotating acoustic drills by the interference of detuned vortices
Jimenez, Noe; González Mateo, Enrique; Camarena, Francisco; Staliunas, Kestutis (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialWe present acoustic drill beams, structured sound beams exhibiting a dynamic intensity distribution that matches the shape of a helix. The intensity distribution rotates along the beam axis with controlled direction and ... -
Sharp acoustic vortex focusing by Fresnel-spiral zone plates
Jimenez, Noe; Romero García, Vicenç; Garcia Raffi, Luis Miguel; Staliunas, Kestutis (2018-05-14)
Article
Accés obertWe report the optimal focusing of acoustic vortex beams by using flat lenses based on a Fresnel- spiral diffraction grating. The flat lenses are designed by spiral-shaped Fresnel zone plates composed of one or several arms. ...
