Kavli Affiliate: Feng Wang | First 5 Authors: Lizhen Qin, Feng Wang, Yun Wang, , | Summary: We propose a new numerical domain decomposition method for solving elliptic equations on compact Riemannian manifolds. One advantage of this method is its ability to bypass the need for global triangulations or grids on the manifolds. Additionally, it […]

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Bo Yang, Renfang Wang, Hong Qiu, | Summary: Deep learning techniques have been used to build velocity models (VMs) for seismic traveltime tomography and have shown encouraging performance in recent years. However, they need to generate labeled samples (i.e., pairs of input and label) to […]

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Hui Zheng, Eric Sivonxay, Max Gallant, Ziyao Luo, Matthew McDermott | Summary: Amorphous materials exhibit unique properties that make them suitable for various applications in science and technology, ranging from optical and electronic devices and solid-state batteries to protective coatings. However, data-driven exploration and design of […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Mit H. Naik, Jonah B. Haber, Jeffrey B. Neaton, Steven G. Louie | Summary: Despite the weak, van-der-Waals interlayer coupling, photoinduced charge transfer vertically across atomically thin interfaces can occur within surprisingly fast, sub-50fs timescales. Early theoretical understanding of the charge transfer is based […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Fabien Defrance, Cecile Jung-Kubiak, John Gill, Sofia Rahiminejad, Ted Macioce | Summary: We present the design, fabrication, and test of a 100 mm diameter flat gradient-index (GRIN) lens fabricated with high-resistivity silicon and combined with three-layer anti-reflection (AR) structures optimized for 160 – 355 GHz. The anti-reflection […]

Golwala | First 5 Authors: Fabien Defrance, Cecile Jung-Kubiak, John Gill, Sofia Rahiminejad, Theodore Macioce | Summary: We present the design, fabrication, and characterization of a 100 mm diameter, flat, gradient-index (GRIN) lens fabricated with high-resistivity silicon, combined with a three-layer anti-reflection (AR) structure optimized for 160-355 GHz. Multi-depth, deep reactive-ion […]
Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Jean-Marc Martin, Junhan Kim, Fabien Defrance, Shibo Shu, Andrew D. Beyer | Summary: We present the optical characterization of two-scale hierarchical phased-array antenna kinetic inductance detectors (KIDs) for millimeter/submillimeter wavelengths. Our KIDs have a lumped-element architecture with parallel plate capacitors and aluminum inductors. The incoming light […]
Kavli Affiliate: Changhuei Yang | First 5 Authors: Pengming Song, Ruihai Wang, Lars Loetgering, Jia Liu, Peter Vouras | Summary: Synthetic aperture radar (SAR) utilizes an aircraft-carried antenna to emit electromagnetic pulses and detect the returning echoes. As the aircraft travels across a designated area, it synthesizes a large virtual aperture to improve image resolution. […]
