Soundiation: A multi-functional GUI-based software in evaluation of the acoustophoresis by the acoustic radiation force and torque on arbitrary axisymmetric objects

Acoustic radiation force and torque arising from wave scattering are commonly used to manipulate micro-objects without contact. We applied the partial wave expansion series and the conformal transformation approach to estimate the radiation force and torque exerted on an axisymmetric particle. Meanwhile, translational and rotational transformations are required to keep the coordinate system consistent [1]. Although these theoretical derivations have been well established, coding the required systems, including generation of the wave function, implementation of the transformations, calculations between modules, etc., is non-trivial and time-consuming. Here, a new open-source, MATLAB-based software, called Soundiation, is provided to address the radiation force and torque while supporting the dynamic prediction of non-spherical particles. The implementation is basically generic, and its applicability is demonstrated through the validation of numerical methods. Furthermore, a graphical user interface is provided so that it can be used and extended easily.
