Semi-analytical model for hollow-core anti-resonant fibers
Frontiers in Physics, 2015 We detailedly describe a recently-developed semi-analytical method to quantitatively calculate light transmission properties of hollow-core anti-resonant fibers (HC-ARFs).

Design and fabrication of extruded retroreflective polymer fibers
Optical Materials Express, 2014 Extruded polymer fibers with submillimeter diameters are considered for tailored optical and near-IR properties. Retroreflection of light is demonstrated. Simulated and measured reflection spectra are compared and found to agree. Additional simulations suggest that retroreflection from gold coated 12-pointed star fibers could exceed retroreflection ...

Design and Fabrication of Monolithic Photonic Crystal Fiber Acoustic Sensor [PDF]
IEEE Sensors Journal, 2018 Single-crystal silicon is an excellent optical and mechanical material, but its properties are compromised by the incorporation of other materials required for functionality or structural support. Here we describe a monolithic silicon acoustic sensor based on a sensing diaphragm with an integrated Photonic Crystal (PC) mirror.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
