Acoustic Wave Trapping in One- Dimensional Axisymmetric Arrays
The existence of acoustic, Rayleigh-Bloch modes in the vicinity of a one-dimensional periodic array of rigid, axisymmetric structures is established with the use of a variational principle. Axisymmetric modes at frequencies below the cut-off frequency are shown to exist for all piecewise smooth structures and non-axisymmetric modes are found for a class of structures whose radial dimension is s...
متن کاملLight Trapping above the Light Cone in One-Dimensional Arrays of Dielectric Spheres
We demonstrate bound states in the radiation continuum (BSC) in a linear periodic array of dielectric spheres in air above the light cone. We classify the BSCs by orbital angular momentum m = 0,±1,±2 according to the rotational symmetry of the array, Bloch wave vector β directed along the array according to the translational symmetry, and polarization. The most simple symmetry protected BSCs ha...
متن کاملAn efficient Wave Based Method for axisymmetric acoustic-poroelastic problems
The most commonly used prediction techniques to study the steady state behaviour of coupled acousticporoelastic problems are based on the Finite Element Method. However, due to the large computational load when frequency increases, these methods are restricted to low frequency problems. Recently, a Wave Based Method was developed to tackle this type of problems in a more efficient way. The meth...
متن کاملLinear Algebra in One-Dimensional Systolic Arrays
Frequently used problems of linear algebra, such as the solution of linear systems, triangular decomposition and matrix multiplication, are computationally extensive. To increase the speed, those problems should be solved with systolic structures, where many processors are used concurrently to compute the result. Since two-dimensional array of processors is very consumptive, considering space a...
متن کاملThree-Dimensional Numerical Modeling of Acoustic Trapping in Glass Capillaries
Acoustic traps are used to capture and handle suspended microparticles and cells in microfluidic applications. A particular simple and much-used acoustic trap consists of a commercially available, millimeter-sized, liquid-filled glass capillary actuated by a piezoelectric transducer. Here, we present a three-dimensional numerical model of the acoustic pressure field in the liquid coupled to the...
