Abstract A tunable hybrid metamaterial absorber (MA) in the microwave band was designed, fabricated and characterized. The MA realized by incorporating a VO 2 film into conventional resonant MA. By thermally triggering insulator–metal phase transition of film, impedance match condition broken deep amplitude modulation about 63.3% to electromagnetic wave absorption achieved. moderate blue-shift resonance frequency observed which is promising for practical applications. This -based exhibits...
Permeability spectra of NiZn ferrite with different microstructures had been resolved into contributions domain wall resonance and spin rotation relaxation. The fitting results permeability dispersion revealed the relationships among resonance, relaxation mechanisms, microstructures. Pcv (power loss) was analyzed by dividing Ph (hysteresis Pe+Pr (eddy current loss residual from frequency dependence power loss. When excited under large flux density, sample larger average grain size closed...
Abstract The bond characteristics, Raman spectroscopy, and microwave dielectric properties of Zn 3‐x Li 2x (BO 3 ) 2 ceramics prepared by solid‐state reaction method were investigated. According to the complex chemical theory, ionicity lattice energy B–O proved contributed more electric polarization phase structure stability than that A‐site bond. Thus, had a dominant effect on constant Q × f values. optimization τ value can be attributed valence. Moreover, shift full width at half maximum...
Magneto-dielectric materials with matched permeability and permittivity are promising candidates as loading to reduce the physical dimensions of low-frequency antennas. In this study, NiCuZn ferrites were prepared by both traditional final-stage sintering process two-step obtain magneto-dielectric materials. It was found that samples sintered tended microstructure dense, homogeneous, small average grain size, which favorable low magnetic dielectric losses. The sample high temperature 950 °C...
Abstract With the emergence of 5G–6G communication technology, miniaturization and integration electronic components are crucial. Ba 3 Ti 4 Nb O 21 (BTN) ceramics with hexagonal structures have attracted special attention due to their high dielectric constant, which shows greater application potential in base stations resonators. However, its sintering temperature low‐quality factors also greatly limit field. In this paper, boric acid (H BO ) as a dopant, was used investigate influence on...
High quality VO2 thin films have been fabricated on silicon substrates using magnetron sputtering by introducing Al2O3 as a buffer. The ultrathin deposited plasma-assisted atomic layer deposition leads to greatly improved crystallinity and textures in films. Dramatic change electrical resistivity (4 orders of magnitude) small thermal hysteresis loop (~4 K) are obtained across the metal–insulator phase transition (MIT). Remarkably, applying perpendicular voltage VO2/Al2O3 based...
The authors show that a current flowing in direction not perpendicular to the layer planes of an exchange-biased spin valve systematically changes exchange bias. bias can be completely reversed when large enough is applied. This effect occurs only initial sweeping magnetic field antiparallel exchange-bias field. attributed recently predicted current-induced torque antiferromagnet and provides evidence support prediction critical smaller than typical value for switching ferromagnet.
