Transmittivity of 2D graded phononic crystals in the frequency and time domains

In this work, we report on the rainbow guiding for the lowest-order antisymmetric Lamb (A 0 ) mode in a phononic crystal plate, where the linear waveguides are

Recently, cavity modes for Love waves, which is a shear horizontal (SH) surface acoustic waves (SAW), are demonstrated in a holey PnC (h-PnC) that consist of square arrayed holes in

On the other hand, the simplicity of the sonic crystals in which only the longitudinal polarization can be excited, is used here to inter- pret, without loss of generality, the

In the inset, we give, after extraction of the incident component, the color map of the modulus of the elastic field at resonance ( f = 467 kHz), in a plane passing at the center of

We have studied surface wave generation on deeply corrugated one-dimensional phononic crystal gratings by di ffraction of acoustic pressure waves incident from water. In the

Generalized Fresnel formulas for reflection and transmission at the phononic crystal boundary have been obtained and used to show that antisymmetric Bloch waves are not excited by

Two surface waves, the generalized Rayleigh wave and the Scholte-Stoneley wave (SSW), may propagate at a plane solid- liquid interface [3].. Results are well established when the

In our opinion, the most crucial observa- tion providing convincing evidence of the effects of the rotational degrees of freedom, the milestone of the Cosserat theory, would be
