Bio-Inspired Compensatory Strategies for Damage to Flapping Robotic Propulsors

Kavli Affiliate: Morteza Gharib | First 5 Authors: Meredith L. Hooper, Isabel Scherl, Morteza Gharib, , | Summary: To maintain full autonomy, autonomous robotic systems must have the ability to self-repair. Self-repairing via compensatory mechanisms appears in nature: for example, some fish can lose even 76% of their propulsive surface without loss of thrust by […]

Flat silicon gradient index lens with 3-layer anti-reflection structures for millimeter and submillimeter wavelengths

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 […]

Hierarchical phased-array antennas coupled to Al KIDs: a scalable architecture for multi-band mm/submm focal planes

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 […]

Ptycho-endoscopy on a lensless ultrathin fiber bundle tip

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. […]

A compact and cost-effective laser-powered speckle visibility spectroscopy (SVS) device for measuring cerebral blood flow

Kavli Affiliate: Changhuei Yang | First 5 Authors: Yu Xi Huang, Simon Mahler, Maya Dickson, Aidin Abedi, Julian M. Tyszka | Summary: In the realm of cerebrovascular monitoring, primary metrics typically include blood pressure, which influences cerebral blood flow (CBF) and is contingent upon vessel radius. Measuring CBF non-invasively poses a persistent challenge, primarily attributed […]
