Observation of ultrasonic Talbot effect in perforated plates

Candelas Valiente, Pilar; Fuster Escuder, José Miguel; Pérez-López, Sergio; Uris Martínez, Antonio; Rubio Michavila, Constanza (Elsevier, 2019)

[EN] The Talbot effect using ultrasonic waves transmitted through a periodic perforated plate is presented. The ultrasonic wave-field at the exit of the perforated plate replicates the perforated pattern at the Talbot ...
On the Role of the Geometrical Parameters in the Ultrasonic Transmission Through Plates with Subwavelength Holes Arrays

Uris Martínez, Antonio; Gómez Lozano, Vicente; Candelas Valiente, Pilar; Belmar Ibáñez, Francisco (Hirzel Verlag (S. Hirzel Verlag), 2014-08)

[EN] This paper presents an overview of the recents studies on the ultrasonic transmission through subwavelength holes arrays. The role of the geometrical parameters of the perforated plates in the transmission features ...
Time-Domain Simulation of Ultrasound Propagation in a Tissue-Like Medium Based on the Resolution of the Nonlinear Acoustic Constitutive Relations

Jimenez, Noe; Camarena Femenia, Francisco; Redondo, Javier; Sánchez Morcillo, Víctor José; Hou, Yi; Konofagou, Elisa E. (Hirzel Verlag (S. Hirzel Verlag)European Acoustics Association (EAA), 2016-09)

A time-domain numerical code based on the constitutive relations of nonlinear acoustics for simulating ultrasound propagation is presented. To model frequency power law attenuation, such as observed in biological media, ...
Ultrasonic transmission through multiple-sublattice subwavelength holes arrays

Estrada Beltrán, Héctor Andrés; Gómez Lozano, Vicente; Uris Martínez, Antonio; Candelas Valiente, Pilar; Belmar Ibáñez, Francisco; Meseguer Rico, Francisco Javier (Elsevier, 2012-03)

The ultrasonic transmission through plates perforated with 2 x 2 or 3 x 3 square array of subwavelength holes per unit cell are studied by numerical simulations. Calculations are obtained by means of a theoretical model ...
