In this paper, a dual-parameter sensor based on surface plasmon resonance (SPR)-photonic crystal fiber (PCF) is proposed, which can be applied in detecting the magnetic field and temperature. sensor, two elliptical channels are designed both sides of core. The left channel (Ch 1) coated with gold film filled fluid (MF) to achieve response temperature using SPR. right 2) as well Ta2O5 improve SPR sensing performance. Finally, Ch 2 polydimethylsiloxane (PDMS) mode characteristics, structural...
A surface plasmon resonance (SPR) sensor comprising photonic crystal fiber (PCF) is designed for magnetic field and temperature dual-parameter sensing. In order to make the SPR detection of effectively, two open ring channels proposed are coated with gold silver layers filled fluid (MF) Polydimethylsiloxane (PDMS), respectively. The analyzed by finite element method its mode characteristics, structure parameters sensing performance investigated. analysis reveals when a range 40-310 Oe 0-60...
Fiber hybridization can effectively solve the localized brittle fracture problem of composite honeycomb, but interaction between different fibers leads to a very complex failure mechanism. Hence, 3D-printed hybrid continuous fiber honeycombs with combination carbon and Kevlar are designed study structural behaviors by experiment simulation method. The experimental samples, including Onyx, carbon, Kevlar, carbon/Kevlar, Kevlar/carbon composites, fabricated based on Markforged 3D printing...
Rigid polyurethane-based foam is an ideal choice for sandwich-panel-filling materials due to its high strength, low thermal conductivity, adhesion, and chemical resistivity. Since sandwich panel often face cyclic mechanical loads during their service, it significant study the design methods of fatigue-resistant rigid polyurethane fatigue failure mechanism improve performance materials. In this study, a rubber powder/polyurethane composite material was prepared by introducing powder,...

Metamaterials refers to a class of artificial materials with special properties. Through its unique geometry and the small size each unit, material can acquire electromagnetic field properties that conventional do not have. Based on these factors, we put forward kind high absorption near-ultraviolet near-infrared wave absorber solar energy. The surface structure designed is composed TiN-TiO2-Al2O3 rectangles disks, substrate Ti-Al2O3-Ti layer. In study band range (0.1–3.0 μm), absorber’s...
An electronic target technology based on a nondiffracting beam for spatial attitude determination is proposed. Automatic orientation of shield tunnel equipment achieved by spatial-coordinates measurement system consisting an and total station. During the measurement, ranging laser sent from It transformed into axicon, spot images are captured charged-coupled device image sensor. Since center has one-to-one mapping to incident direction laser, can be obtained via fitting images. When this...
This paper presents a graphene metamaterial absorber based on impedance matching. A finite difference in time domain (FDTD) method is used to achieve theoretically perfect absorption the mid-infrared band. basis created for multiband stable high of mid-infrared. The designed composed graphene, dielectric layer, gold plane, and silicon substrate, separately. incident source can be utilized stimulate resonance peaks from 2.55 4.15 μm. simulation results show that has three exceeding 99% at λ1...
