This study innovatively presents a hollow-core anti-resonant fiber integrating double-tube nesting and single-layer wall. Featuring an exclusive two-layer cladding configuration along with outer circular ring, it differs significantly from traditional fibers. After careful parameter optimization, at 1.55 μm wavelength, the shows excellent performance. Its confinement loss drops to 0.00088 dB/km, 1–2 orders lower than ones. The proportion between of lowest higher-order mode that fundamental...
To improve the ballistic simulation accuracy of ceramic composite armors and glass (transparent armors) against small-caliber armor piercing bullets, new FEM (finite element method) -SPH (smooth particle hydrodynamics) coupled model was proposed, which replaced JC (Johnson-Cook) material armor-piercing-bullet core traditional FEM-SPH with SPH JH2 (Johnson-Holmquist-ceramics) model. The results show that can effectively simulate bullet fragmentation reduce calculation amount. So it...
