The atmospheric pressure low-temperature plasma jet (APPJ) can generate a wide variety of excited and active particles, with broad application prospects. Due to the strong spatiotemporal distribution characteristics of particles, the physical and chemical properties of plasma jets can be adjusted by changing the type and ratio of working gas, which is crucial for improving jet treatment efficiency and achieving specific treatment effects. This article innovatively analyzes the variations in the spatial distribution, intensity distribution, and activation region distribution of short-lived active substances that are crucial in the application of plasma jets under different gas backgrounds. Under the context of multiple variables, the physical characteristics of the plasma jets are comprehensively analyzed. The results show that the addition of N2 and O2 will weaken the discharge current and power, especially oxygen. After doping with 1% nitrogen, the jet length remains basically unchanged, but after doping with 1% oxygen, the jet length sharply decreases. Most active substances are concentrated at the nozzle of the jet pipe. The activation region of $mathrm {OH}(mathrm {A}^{2}Sigma ^{+}to mathrm {X}^{2}{Pi })$ is significantly lower than that of $mathrm {N}_{2}(mathrm {C}^{3}Pi _{mathrm {u}}to mathrm {B}^{3}Pi _{mathrm {g}})$ . As the N2 content increases from 0% to 1%, the activation region of $mathrm {OH}(mathrm {A}^{2}Sigma ^{+}to mathrm {X}^{2}Pi)$ decays from 17 to 12 mm and the activation region of $mathrm {N}_{2}(mathrm {C}^{3}{Pi }_{mathrm {u}}to mathrm {B}^{3}Pi _{mathrm {g}})$ remains unchanged, but the intensity of $mathrm {N}_{2}(mathrm {C}^{3}Pi _{mathrm {u}}to mathrm {B}^{3}Pi _{mathrm {g}})$ spectral line rises rapidly. As the O2 content increases from 0% to 0.1%, the activation region of $mathrm {OH}(mathrm {A}^{2}{Sigma }^{+}to mathrm {X}^{2}{Pi)}$ has decayed below 10 mm. The intensity of $mathrm {N}_{2}(mathrm {C}^{3}{Pi }_{mathrm {u}}to mathrm {B}^{3}Pi _{mathrm {g}})$ spectral extremely reduced by 48%. The increase in N2 content will lead to an increase in vibration and rotation temperature, while O2 is the opposite. From the axial spatial distribution, the vibrational temperature does not change much, but the rotational temperature decreases with increasing distance from the electrodes and eventually reaches equilibrium with the room temperature of 295 K.

Permanent magnet (PM) linear motor is widely used in the electromagnetic launch system due to the merits of high thrust and rapid response. Inheriting the advantages of linear motor, the PM arc-linear motor (PMAM) has been recognized as an eminent competitor for driving servo turntables and large telescope. This article designs a dual-PM excited PMAM (DPM-PMAM) having different PM arrangements and three-unit distributed complementary structure. Benefiting from the special stator-PM layouts, the DPM-PMAM exhibits the essential flux concentration effect, which contributes to enhance the torque capability. The motor topology and working principle of the studied DPM-PMAM are introduced. The feasible stator slot/rotor pole combinations and the major design parameters are optimized for improving electromagnetic performances. Then, the DPM-PMAM is quantitatively compared with the slot-PM excited PMAM (SPM-PMAM) and the yoke-PM excited PMAM (YPM-PMAM) based on the optimal designs. By comparison, it is found that the DPM-PMAM shows the improved average torque and good overload capability. Finally, the 2-D finite-element (FE) predicted results are validated by 3-D FE results.

Plasma generated by a submerged arc has great potential in wastewater treatment. Carbon is widespread in nature. It is easily acquired and biocompatible. In this article, a low-voltage submerged arc generated by contact-separate of two electrodes is proposed to decompose methylene blue (MB). The process achieved a removal efficiency of 92.9% after 15 min treatment. The emission spectrum of the submerged arc indicated that active particles such as $cdot $ OH radicals, oxygen atoms, and hydrogen peroxide (H2O2) have been produced. Additionally, in the process of arc treatment, the wavelength of the absorption peak of MB solution shifted toward ultraviolet region. It indicated the demethylation of the MB molecules. The eroded particles from the graphite electrodes were also examined, and the carbon quantum dots were observed. Furthermore, micro-scale fibrous entangled particles and layered particles with abundant pore structures were observed. These results demonstrate that the eroded particles own an absorption ability for MB, continuing decolorization of the treated solution without additional active particles generated by the submerged arc plasma.

As frequency resources become increasingly scarce, the need to develop miniaturized, dual-band filters for improving spectrum utilization in broadband communications have become urgent. In this article, we introduce a novel approach for designing a dual-band bandpass filter (BPF) using a hybrid technique that combines substrate-integrated waveguide (SIW), spoof surface plasmon polariton (SSPP), and complementary split ring resonator (CSRR) technologies. The substrate-integrated plasmonic waveguide (SIPW) is created by etching meander-slot SSPP structures onto the top layer of the SIW. This design reduces both the lateral and longitudinal dimensions without adding complexity. By etching CSRRs onto the back of the SIW, the filter achieves strong electromagnetic coupling and narrowband suppression, resulting in a dual-band BPF with operating frequencies of 7–8.1 and 10–11.2 GHz. To validate this design, we fabricated and measured a prototype. The results demonstrate that the proposed SIPW BPF exhibits exceptional filtering performance, with a return coefficient of more than −10 dB and an insertion loss (IL) of less than 1.7 dB in both passbands. In adddition, the designed BPF features wide passband and stopband characteristics.
