    A fundamental Lagrangian approach to transformation acoustics and spherical spacetime cloaking 
    Tung ., Michael Ming-Sha (European Physical Society, 2012)
    [EN] Transformation acoustics centers on the construction of advanced acoustic devices by combining mathematical transformation techniques with the engineering of acoustic metamaterials. We show how di¿erential-geometric ...

    Acoustics in 2D Spaces of Constant Curvature 
    Tung, Michael Ming-Sha; Gambi, José M.; María Luisa García del Pino (Springer, 2016-06-17)
    [EN] In this work, we will consider a locally homogeneous and isotropic (2+1)D spacetime of Robertson-Walker type and therefore with underlying de Sitter space.

    Analogue transformation acoustics and the compression of spacetime 
    García Meca, Carlos; Carloni, Sante; Barceló, Carlos; Jannes, Gil Georges Paul; Sánchez-Dehesa Moreno-Cid, José; Martínez Abietar, Alejandro José (Elsevier, 2014-08)
    A recently developed technique known as analogue transformation acoustics has allowed the extension of the transformational paradigm to general spacetime transformations under which the acoustic equations are not form ...

    Analogue Transformations in Physics and their Application to Acoustics 
    García Meca, Carlos; Carloni, S.; Barcelo, C.; Jannes, G.; Sánchez-Dehesa Moreno-Cid, José; Martínez Abietar, Alejandro José (Nature Publishing Group, 2013-06-18)
    Transformation optics has shaped up a revolutionary electromagnetic design paradigm, enabling scientists to build astonishing devices such as invisibility cloaks. Unfortunately, the application of transformation techniques ...

    Broadband Acoustic Cloaking within an Arbitrary Hard Cavity 
    Kan, Weiwei; García Chocano, Víctor Manuel; Cervera Moreno, Francisco Salvador; Liang, B.; Zou, X.Y.; Yin, L.L.; Cheng, Jianchun; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2015-06-26)
    This paper reports the design, fabrication, and experimental validation of a broadband acoustic cloak for the concealing of three-dimensional (3D) objects placed inside an open cavity with arbitrary surfaces. This 3D cavity ...

    Gravitational frequency shifts in transformation acoustics 
    Tung, Michael Ming-Sha; Weinmüller, Ewa Barbara (European Physical Society, 2013-03)
    In metamaterial acoustics, it is conceivable that any type of fine-tuned acoustic properties far beyond those found in nature may be transferred to an appropriate medium. Effective design and engineering of these modern ...

    Space time transformation acoustics 
    García Meca, Carlos; Carloni, S.; Barceló, C.; Jannes, G.; Sánchez-Dehesa Moreno-Cid, José; Martínez Abietar, Alejandro José (Elsevier, 2014-07)
    A recently proposed analogue transformation method has allowed the extension of transformation acoustics to general space-time transformations. We analyze here in detail the differences between this new analogue transformation ...
