acoustotreams -- A Python package for acoustic-wave scattering based on the -matrix method
Nikita Ustimenko, Carsten Rockstuhl
The transition-matrix (-matrix) method has established itself as a prominent technique for computing the scattering response from spatially localized objects. The suitability be…
Lattice-induced sound trapping in biperiodic metasurfaces of acoustic resonators
Nikita Ustimenko, Andrey B. Evlyukhin, Vicky Kyrimi +2
A referential example of a physical system that supports bound states in the continuum (BICs) with an infinite quality factor ( factor) is a metasurface of discrete scatterers (…
Optimal multipole center for subwavelength acoustic scatterers
Nikita Ustimenko, Carsten Rockstuhl, Alexander V. Kildishev
The multipole expansion is a powerful framework for analyzing how subwavelength-size objects scatter waves in optics or acoustics. The calculation of multipole moments traditionall…
