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…
The art of finding the optimal scattering center(s)
Alexander V. Kildishev, Karim Achouri, Daria Smirnova
The efficient use of a multipole expansion of the far field for rapid numerical modeling and optimization of the optical response from ordered and disordered arrays of various stru…
