Soft magnetic materials are a kind of promising for antenna substrates because their permeability and permittivity both greater than unity. However, properties would deteriorate dramatically as the frequency reaches 1 GHz owing to Snoek limit domain wall resonance, thus limiting application at high frequency. Here, we report low-dimensional soft composite (SMC) prepared by FeB nanochains, achieving optimized loss tangent (tanδμ) 0.09 real part (μ′) 3.3 GHz, which is more competitive...
Abstract In this study, spherical amorphous Fe–B submicron particles were synthesized via aqueous chemical reduction, and a composite with mass fraction of 80% was prepared by compounding them polyurethane. By measuring the electromagnetic parameters calculating microwave absorption properties, we found that had excellent performance in frequency range 18–26.5 GHz. When absorber 0.88 mm thick, reflection loss (RL) peak reached maximum (−47.94 dB) bandwidth (RL < −10 5.01 The mechanism K...
The high-performance electromagnetic (EM) wave absorption material Ba(CoTi) x Fe 12–2 O 19 @BiFeO 3 was prepared by solid-state reaction, and its EM properties were deeply studied. results revealed that could obtain excellent in hundreds of megahertz adjusting the Co 2+ –Ti 4+ content. best comprehensive property obtained for = 1.2, where optimal reflection loss ( RL ) value reaches –30.42 dB at about 600 MHz with thickness 3.5 mm, corresponding effective band covers frequency range 437...
Abstract. In the context of non-standard blade geometries knife-like tools with tapered cutting edges where width surface varies feed, there is limited research on predicting grinding forces considering changing contact line. To enhance accuracy during tools, a novel analytical-regression correction method proposed. This employs an analytical approach to analyze varying line between wheel and tool grinding, enabling determination irregularly shaped zones. By introducing exponential...
