Bound States-to-Bands in the Continuum in Cylindrical Granular Crystals
Yeongtae Jang, Seokwoo Kim, Dongwoo Lee +2
We theoretically investigate and experimentally demonstrate that genuine bound states in the continuum (BICs) -- polarization-protected BICs -- can be completely localized within f…

Demonstrating a Bi-directional Asymmetric Frequency Conversion in Nonlinear Phononic Crystals
Yeongtae Jang, Beomseok Oh, Eunho Kim +1
Beyond the constraints of conservative systems, altering wave propagation frequency emerges as a crucial factor across diverse physical domains. This Letter demonstrates bi-directi…
