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…
Broken-symmetry phenomena enhanced by quasi-bound states in the continuum
Jan David Fischbach, Lukas Rebholz, Nikita Ustimenko +3
Many of the most powerful and elegant models in physics are grounded in symmetries. In electrodynamics, for example, geometric symmetries govern the observable effects of light-mat…
Singular value decomposition to describe bound states in the continuum in periodic metasurfaces
Nikita Ustimenko, Ivan Fernandez-Corbaton, Carsten Rockstuhl
Understanding how bound states in the continuum (BICs) emerge in periodic metasurfaces is essential for the controlled design of high-Q resonances and their systematic manipulation…
Ultrasonic metamaterial at MHz frequencies using microstructured glass
Oscar Demeulenaere, Nikita Ustimenko, Athanasios G. Athanassiadis +3
Acoustic metamaterials enhance traditional material properties through microstructure engineering, providing new opportunities to shape sound fields in applications ranging from bi…
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…
