Actively controlling the infrared (IR) emissivity of materials is critical for numerous applications, such as radiative cooling and thermal camouflage. Multilayer graphene (MLG) has shown significant potential a functional...
Mathematical modeling of the combined side and top blowing AOD refining process stainless steel has further been studied. A new model proposed is generally based on analysis assumptions made for in our previous investigation. Particularly, heat transfer characteristics vessel are analyzed terms two-dimensional transient heat-conduction problems composite walls. The mass balances system more comprehensively precisely performed. applied to 28 heats 304-grade austenitic a 120 t converter....
We theoretically and experimentally proposed the generation method of third-order orbital angular momentum (OAM) modes with reduced losses by cascading two adiabatic mode selective couplers (MSCs), in which LP11 produced as an excitation was utilized to generate a higher-order (LP31). The minimum excess loss insertion cascaded MSCs were 3.7 dB 5.3 dB, had been greatly compared single MSC. Then, OAM turned from LP31 amplified all-fiber system, maximum gain after amplification can be achieved...
We fabricate a few-mode polarization-maintaining fiber (FM-PMF) and present technique for generating circularly polarized (CP) vortex beam, carrying orbital angular momentum (OAM) spin (SAM), by twist method. By controlling the direction of twist, right-handed (RCP) OAM+1 mode with purity ~96.2% polarization extinction ratio (PER) ~0.75 dB, as well left-handed (LCP) OAM-1 ~95.3% PER ~0.82 dB can be selectively obtained. Additionally, twisted FM-PMF is encapsulated CP converter, operational...
We investigate a two-mode polarization maintaining fiber (TM-PMF) imposed by torsion. It has been demonstrated that the eigenmodes of twisted TM-PMF will convert to ${\text{HE}}_{{\text{21}}}^{{ \pm }}$ vortex modes and TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> /TE with gradually increasing twist rate using finite element method; Especially, can be generated orbital angular momentum. Compared untwisted fiber, caused torsional...
