General Method for Evaluation of Stop-Bands of Periodic Structures with Symmetric Unit Cells
Alexander Hvatov, Mariia Krasikova, Aleksandra Pavliuk +1
The mirror symmetries of a periodic unit cell are exploited to decompose the standing-wave eigenproblem at the high-symmetry vertices of the Brillouin zone into four independent su…
Reconfigurable Manipulation of Sound with a Multi-material 3D-Printed Origami Metasurface
Dinh Hai Le, Felix Kronowetter, Yan Kei Chiang +3
The challenge in reconfigurable manipulation of sound waves using metasurfaces lies in achieving precise control over acoustic behavior while developing efficient and practical tun…
Reconfigurable Acoustic Metalens with Tailored Structural Equilibria
Dinh Hai Le, Felix Kronowetter, Yan Kei Chiang +3
The ability to concentrate sound energy with a tunable focal point is essential for a wide range of acoustic applications, offering precise control over the location and intensity…
Acoustic Bound States in the Continuum in Coupled Helmholtz Resonators
Mariia Krasikova, Felix Kronowetter, Sergey Krasikov +6
Resonant states underlie a variety of metastructures that exhibit remarkable capabilities for effective control of acoustic waves at subwavelength scales. The development of metama…
