Hyperspectral interference tomography of nacre
Jad Salman, Cayla A. Stifler, Alireza Shahsafi +12
Structural characterization of biologically formed materials is essential for understanding biological phenomena and their environment, and generating new bio-inspired engineering…
Modulation of Negative Index Metamaterials in the Near-IR Range
Evgenia Kim, Wei Wu, Ekaterina Ponizovskaya +5
Optical modulation of the effective refractive properties of a "fishnet" metamaterial with a Ag/Si/Ag heterostructure is demonstrated in the near-IR range and the associated fast d…
Broadband light extraction from near-surface NV centers using crystalline-silicon antennas
Minjeong Kim, Maryam Zahedian, Wenxin Wu +9
We use crystalline silicon (Si) antennas to efficiently extract broadband single-photon fluorescence from shallow nitrogen-vacancy (NV) centers in diamond into free space. Our desi…
MAGE: Model-Level Graph Neural Networks Explanations via Motif-based Graph Generation
Zhaoning Yu, Hongyang Gao
Graph Neural Networks (GNNs) have shown remarkable success in molecular tasks, yet their interpretability remains challenging. Traditional model-level explanation methods like XGNN…
Ultrathin broadband reflective optical limiter
Chenghao Wan, Zhen Zhang, Jad Salman +7
Optical limiters are nonlinear devices that feature decreasing transmittance with increasing incident optical intensity, and thus can protect sensitive components from high-intensi…
Molecular Representation Learning via Heterogeneous Motif Graph Neural Networks
Zhaoning Yu, Hongyang Gao
We consider feature representation learning problem of molecular graphs. Graph Neural Networks have been widely used in feature representation learning of molecular graphs. However…
