The electronic structure of lead-halide perovskite nanocrystals (NCs) could be tailored to enable the tunable photoluminescence (PL) in window from ultraviolet-visible-near infrared by halogen ion exchange reaction, which has been considered as most effective and convenient post-treatment method for manipulating chemical composition perovskite. However, NCs with such are generally not stable, mechanism how reaction kinetic influences stability well demonstrated. In this work, we show that Cl...
Abstract The combination of tunable and static absorption at different frequency bands is urgently desired for radar stealth technology yet still remains a challenge. This study proposes novel strategy establishing window in wideband absorber. A structural prototype designed with layer, resistive reflection backplane. By applying biasing voltage to the absorber can be dynamically controlled 2–6 GHz. After integration consistently stabilizes 6–18 measured spectra three planar specimens align...
A multifunctional metasurface is capable of manipulating electromagnetic waves and achieving kaleidoscopic functions flexibly, which significantly improves the integration utilization a single has become one hotspots in electromagnetics. However, majority designs to date can only operate for limited polarization states half-space are difficult show diverse at same time, restrict widespread applications metadevices. Herein, an inspiring strategy chiral transmission-reflection-selective...
The low RCS level out of operating band is urgent for radome while keeping its communication window. To solve this problem, we propose a frequency selective rasorber (FSR) that exhibits pass-band between two absorption bands in paper. surface currents on finite metallic wire media analyzed firstly to elaborate transverse standing waves mechanism. High-efficiency and broadband can be achieved by loading lumped resistors at high amplitude waves. By delicately engineering the versus frequency,...
In this paper, the idea of spoof surface plasmon polaritons (SSPPs) realized by unidirectional carbon fibers (CFs) arrays are proposed and investigated. A structure/function integrated sandwich structure (SISS) with excellent microwave absorption mechanical properties was designed. It is composed two corrugation layers gradient CFs between them. According to our research, performance can be modulated adjusting parameters. As angle increases, becomes better whether in normal or oblique...
Edge scattering is one of the main sources for metal objects, especially those with thin front edges. In this paper, we propose to suppress edge back-scattering electromagnetic (EM) waves using coding metasurface purfle, which based on principle cancellation, rather than absorption. To end, two split-ring resonators (SRRs) are designed have a π phase difference, as 0- and 1-element metasurface. The fixed plate, significant EM polarized along direction. Due anti-phase elements, suppressed by...
In this work, a metasurface-based radome composite (MRC) with customized electromagnetic (EM) functions is proposed. By employing beam-scattering mechanism, high transmission at 2–4 GHz and significant radar cross-section (RCS) reduction 8–18 are achieved. The MRC prototype features sandwiched construction fabricated using quartz fiber-reinforced (QFRC) skins, polymethacrylimide (PMI) foam cores, silver-based frequency selective surface (FSS) screens. calculation, simulation, measured...
Abstract The microstructure of thermal barrier coatings (TBC) plays an important role in the cycling behavior TBCs. In this study, ceramic with different pore structures were prepared by atmospheric plasma spraying (APS). Graphite morphology was used as former to adjust structure coatings. Then, TBCs characterized. By depositing a porous 8YSZ layer on conventional layer, life can be improved. However, when porosity increased about 30%, detached from under after several cycles. An elastic...
The excitation and propagation of spoof surface plasmon polaritons (SSPPs) have always been the hot topics. emergence phase gradient metasurface (PGM) makes efficiency SSPPs higher. However, polarization state incident waves determines mode excited SSPPs. In general, single (TE or TM) will be coupled for linear polarized (LP) illumination, hybrid modes circular (CP) illumination. order to get rid restriction waves' polarization, we propose combined metasurfaces obtain under LP incidence....
