Underwater Willis lens for broadband low-frequency focusing
Beomseok Oh, Dongwoo Lee, Yeon-Seong Choo +4
Broadband underwater sound focusing in the low-frequency range is essential for various applications such as battery-free environmental monitoring and sensing. However, achieving l…
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…
Conformally mapped black hole effect in elastic curved continuum
Dongwoo Lee, Yiran Hao, Jeonghoon Park +3
We present a black hole effect by strategically leveraging a conformal mapping in elastic continuum with curved-space framework, which is less stringent compared to a Schwarzschild…
Topologically non-trivial photonic surface degeneracy in a photonic metamaterial
Minkyung Kim, Dasol Lee, Dongwoo Lee +1
The recent development of topological photonics has revealed a variety of intriguing phenomena such as Weyl degeneracy. However, topologically non-trivial degeneracy with higher di…
