Acoustic Willis metamaterials beyond the passivity bound
Choonlae Cho, Xinhua Wen, Namkyoo Park +1
Acoustic bianisotropy, also known as the Willis parameter, expands the field of acoustics by providing nonconventional couplings between momentum and strain in constitutive relatio…
Topological hyperbolic lattices
Sunkyu Yu, Xianji Piao, Namkyoo Park
Non-Euclidean geometry, discovered by negating Euclid's parallel postulate, has been of considerable interest in mathematics and related fields for the description of geographical…
B1+ Homogenization in 7T MRI Using Mode-shaping with High Permittivity Materials
Yunchan Hwang, Hansol Noh, Minkyu Park +2
Ultra high field (UHF) brain MRI has proved its value by providing enhanced SNR, contrast, and higher resolution derived from the higher magnetic field (B0). Nonetheless, with the…
Chirality in non-Hermitian photonics
Sunkyu Yu, Xianji Piao, Namkyoo Park
Chirality is ubiquitous from microscopic to macroscopic phenomena in physics and biology, such as fermionic interactions and DNA duplication. In photonics, chirality has traditiona…
Terahertz nano antenna enabled early transition in VO2
Young-Gyun Jeong, Ji-Soo Kyoung, Jae-Wook Choi +6
We study terahertz transmission through nano-patterned vanadium dioxide thin film. It is found that the patterning allows the lowering of the apparent transition temperature. For t…
