    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 ...

    Diffusive-light invisibility cloak for transient illumination 
    Orazbayev, Bakhtiyar; Beruete, Miguel; Martínez Abietar, Alejandro José; García Meca, Carlos (American Physical Society, 2016-12-22)
    Invisibility in a diffusive-light-scattering medium has been recently demonstrated by employing a scattering-cancellation core-shell cloak. Unlike nondiffusive cloaks, such a device can be simultaneously macroscopic, ...

    Dynamically tunable transformation thermodynamics 
    García Meca, Carlos; Barceló, Carlos (IOP Publishing, 2016-04)
    Recently, the introduction of transformation thermodynamics has provided a way to design thermal media that alter the flow of heat according to any spatial deformation, enabling the construction of novel devices such as ...

    Full three-dimensional isotropic transformation media 
    García Meca, Carlos; Ortuño Molinero, Rubén; Martí Sendra, Javier; Martínez Abietar, Alejandro José (IOP Publishing: Open Access Journals, 2014-02-21)
    We present a method that enables the implementation of full three-dimensional (3D) transformation media with minimized anisotropy. It is based on a special kind of shape-preserving mapping and a subsequent optimization ...

    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 ...

    Imaging Cloaked Objects: Diffraction Tomography of Realistic Invisibility Devices 
    Díaz-Fernández, Francisco Javier; Martí Sendra, Javier; García Meca, Carlos (John Wiley & Sons, 2023-02)
    [EN] Invisibility cloaks have become one of the most outstanding developments among the wide range of applications in the field of metamaterials. So far, most efforts in invisibility science have been devoted to achieving ...

    Towards the full control of sound with sonic crystals and acoustic metamaterials 
    Torrent Martí, Daniel (Universitat Politècnica de València, 2008-09-12)
    El objetivo de este trabajo ha sido obtener expresiones matemáticas para los parámetros elásticos y acústicos efectivos de sistemas heterogéneos en el límite de homogeneización, lo que ha permitido el diseño de nuevos ...
