Acoustic levitation permits non-contact handling of mm-scale samples. To improve its applicability, we did a simulation study to optimize orientation control of a sample residing in a phased array levitator. The acoustic forces and torques on asymmetric samples in asymmetric traps were determined by solving the acoustic scattering problem with the boundary element method. The angular stiffness of the trap was mapped as a function of the field shape. This allowed us to choose the optimal…

Multifrequency Acoustic Levitation

Acoustic levitation permits non-contact particle manipulation. The position and orientation of the levitated particle can be controlled by altering the acoustic field. Existing acoustic levitators

BEM-FEM Simulation of Acoustic Levitation Dynamics with Phased Arrays

We present a simulation model that can be used to study the movement of an object in an acoustic levitator. The model uses the boundary element method (BEM) to compute the levitator's acoustic field,

4π Scatterometer: A new technique for understanding the general and complete scattering properties of particulate media

Knowing the optical properties of a sample is important in many scientific fields, such as space science, climate studies, and medicine. In many of these applications, the samples are fragile, unique



Acoustic Lock: Position and orientation trapping of non-spherical sub-wavelength particles in mid-air using a single-axis acoustic levitator

We demonstrate acoustic trapping in both position and orientation of a non-spherical particle of sub-wavelength size in mid-air. To do so, we multiplex in time a pseudo-one-dimensional vertical

Holographic acoustic elements for manipulation of levitated objects

The phases used to drive an ultrasonic phased array are optimized and it is shown that acoustic levitation can be employed to translate, rotate and manipulate particles using even a single-sided emitter.

Omnidirectional microscopy by ultrasonic sample control

Omnidirectional microscopy (OM) is an emerging technology capable of enhancing the three-dimensional (3D) microscopy widely applied in life sciences. In OM, the precise position and orientation

Airborne chemistry: acoustic levitation in chemical analysis

A unique path to miniaturisation is described, that is, the use of acoustic levitation in analytical and bioanalytical chemistry applications, where acoustic or ultrasonic levitation fulfils all requirements for analytical chemistry applications.

Acoustic physics: Suspended by sound

Ultrasound waves can levitate heavy balls of tungsten. This contact-free method of keeping items suspended in the air can be applied to the investigation and processing of new materials.

Scattering And Absorption of Light in Planetary Regoliths.

Theoretical, numerical, and experimental methods are presented for multiple scattering of light in macroscopic discrete random media of densely-packed microscopic particles to interpret astronomical observations for asteroid Vesta and comet 67P/Churyumov-Gerasimenko.
