    Sub-Diffractive Acoustic Vortices by Nonlinear Mixing 
    Jimenez, Noe; Ealo, Joao; Muelas-Hurtado, Rubén; Duclos, Aroune; Romero-García, Vicent (IEEE, 2021-09-16)
    [EN] Vortex beams, characterized by a collimated wavefront with a phase dislocation at their principal axis, have found practical applications to construct acoustic tweezers for particle trapping and manipulation, or ...

    Sub-wavelength acoustical vortex beams using self-demodulation 
    Jimenez, Noe; Ealo, Joao; Muelas-Hurtado, Rubén D.; Duclos, Aroune; Romero-García, Vicent (American Physical Society, 2021-05-13)
    [EN] Acoustic vortices with subwavelength dimensions and tunable topological charge are theoretically and experimentally synthesized at distances far beyond the Rayleigh diffraction length of the source, using self-demodulation. ...
