Acoustic metamaterial models on the (2+1)D Schwarzschild plane

Tung, Michael Ming-Sha; Weinmüller, Ewa B. (Elsevier, 2019-01-15)

[EN] Recent developments in acoustic metamaterial engineering have led to the design and fabrication of devices with formidable properties, such as acoustic cloaking, superlenses and ultra-sound waves. Artificial materials ...
Curvature conditions for spatial isotropy

Tzanavaris, Kostas; Amaro-Seoane, Pau (Elsevier, 2022-08)

[EN] In the context of mathematical cosmology, the study of necessary and sufficient conditions for a semi-Riemannian manifold to be a (generalized) Robertson-Walker space-time is important. In particular, it is a requirement ...
Modelling acoustics on the Poincaré half-plane

Tung, Michael Ming-Sha (Elsevier, 2018)

[EN] Novel advances in the field of metamaterial research have permitted the engineering of devices with extraordinary characteristics. Here, we explore the possibilities in transformation acoustics to implement a model ...
Modelo para el trazado de una carretera entre dos paraboloides

Lorente Arreba, Víctor José; Jiménez Fernández, Eduardo; Vicent Ferrando, Lorena (Universitat Politècnica de València, 2013-06-02)

[EN] We present a classroom task that consists to model the path of the road between two paraboloid surfaces. The purpose of this paper is to teach the differential calculus using mathematical modeling as a teaching tool. ...
The Relativistic Anharmonic Oscillator within a Double-Well Potential

Tung, Michael Ming-Sha; Rapp, Frederic (Universitat Politècnica de València, 2022-07-15)

[EN] Non-harmonic oscillations described by a double-well potential allow to model various physical phenomena and provide insight into their properties without overly simplifying the problem, thereby extending the more ...
The variational principle in transformation optics engineering and some applications

García Meca, Carlos; Tung, Michael Ming-Sha (Elsevier, 2013)

Transformation optics specializes in the engineering of advanced optical devices, and in combination with differential geometry it allows to control electromagnetic fields with artificial media in an unprecedented manner. ...
Varietats lorentzianes en la representació dels estats estacionaris dels àtoms hidrogenoides en la teoria de de Broglie - Bohm. Uns models heurístics

Gómez Blanch, Guillem (Universitat Politècnica de València, 2021-11-10)

[EN] This thesis aims to find out the applicability of Lorentzian geometry to represent the motion of the electron in hydrogen atoms according to the de Broglie-Bohm quantum theory (dBB). It starts from the observation ...
