Efficient Simulation of Spatio-temporal Dynamics in Ultrasonic Resonators

Alonso-Jordá, Pedro; Peinado Pinilla, Jesús; Pérez Arjona, Isabel; Sánchez Morcillo, Víctor José (Springer Verlag (Germany), 2011)

The simulation in computers of the evolution of pressure and temperature inside a cavity when acoustic energy is injected results in a very stiff and high time consuming application. The split-step method used for the ...
Experimental realization of broadband tunable resonators based on anisotropic metafluids

Spiousas, Ignacio; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2011-06-13)

This letter demonstrates the mechanical tuning of modes confined in two-dimensional acoustic cavities based on anisotropic metafluids. The employed metafluids have been designed with effective parameters such that the ...
Tunable wideband bandstop acoustic filter based on two-dimensional multiphysical phenomena periodic systems

Romero García, Vicente; Sánchez Pérez, Juan Vicente; García-Raffi, L. M. (American Institute of Physics (AIP), 2011)

The physical properties of a periodic distribution of absorbent resonators is used in this work to design a tunable wideband bandstop acoustic filter. Analytical and numerical simulations as well as experimental validations ...
