    Acoustical hooks: A new subwavelength self-bending beam 
    Rubio Michavila, Constanza; Tarrazó-Serrano, Daniel; Minin, Oleg V.; Uris Martínez, Antonio; Minin, Igor V. (Elsevier, 2020-03)
    [EN] In this work, we report the first experimental observation of a new type of near-field curved acoustic beam confirmed by simulations. This new curved acoustical beam is generated by asymmetric distribution of the ...

    Application of Phase-Reversal Fresnel Zone Plates for Improving The Elevation Resolution in Ultrasonic Testing with Phased Arrays 
    Dolmatov, Dmitry O.; Tarrazó-Serrano, Daniel; Filippov, German A.; Minin, Igor V.; Minin, Oleg V.; Sednev, Dmitry A. (MDPI AG, 2019-12)
    [EN] Currently, phased arrays have found wide application in ultrasonic nondestructive testing. Volumetric results provided by the inspections with linear phased arrays have low lateral resolution in the elevation direction ...

    Fractal lenses based on Cantor binary sequences for ultrasound focusing applications 
    Pérez-López, Sergio; Fuster Escuder, José Miguel; Candelas Valiente, Pilar; Rubio Michavila, Constanza (Elsevier, 2019)
    [EN] In this work, we demonstrate the application of Cantor fractal lenses in acoustics. The Cantor Zone Plate (CZP), previously introduced in optics, is designed from a conventional Fresnel Zone Plate (FZP) using a binary ...

    Sound Scattering by Lattices of Heated Wires 
    Ivanov Angelov, Mitko (Universitat Politècnica de València, 2016-05-02)
    [EN] The aim of this work is to demonstrate theoretically and experimentally how acoustic wave propagation can be controlled by temperature gradients. Starting with the simplest case of two hot wires in air the study extends ...
