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.

In this article, a kind of armature ablation calculation method is presented considering mechanical (high-speed friction transformation, friction) and magnetohydrodynamic and so on. The main features of this approach simplify the armature material solid-build-gas phase transformation model, high-speed friction, and wear model and the contact surface magnetohydrodynamic film model. The new standard to the armature ablation is that not only the element material melting point temperature is reached but also has a minimum plastic strain; at this moment, this element is recognized as dissolution. Finally, the simulation results are compared with the experimental results; both are in good agreement, so as to verify the correctness of this algorithm.

The launch performance of an electromagnetic induction coilgun is influenced by the structural parameters of the coils and the armature, as well as the timing of the trigger parameter. These parameters are interdependent, making optimization design challenging. To address these issues, this article proposes a sequential orthogonal optimization design method for high-speed electromagnetic induction coilgun based on armature updating, which uses the trigger strategy of the sequential advance of position and determines optimization indices and their weight by analytic hierarchy process (AHP), including peak velocity, maximum launch efficiency, and waveform stability. By updating the armature sequentially, an orthogonal table for five structural parameters and one trigger parameter is optimized. By setting constraints on armature length, coil turns, and power supply voltage, the optimization design of a 10-stage high-speed induction electromagnetic coilgun is realized. The results show that after optimization, with constant total energy storage and the number of stages, the peak speed increased from 501.03 to 832.60 m/s, and the maximum launch efficiency improved from 13.24% to 25.56%.

In the process of sliding electrical contact, the current would cluster locally under the effect of velocity skin effect (VSE) and complex damage on the contact interface would occur under the coupling effect of Joule heat, frictional heat, and high-speed impact, which would seriously affect the safety and stability of sliding electrical contact systems. In this article, a modified smoothed particle hydrodynamics (SPHs) method is introduced into the study of the damage to the sliding electrical contact interface while considering the VSE in the process of sliding electrical contact. First, the magnetic induction equation is introduced into the SPH method. Then, the distribution characteristics of multiple physical fields are simulated, and the effects of velocity while considering the VSE are analyzed. Furthermore, considering the nonuniform distribution of current caused by the VSE, the effects of the vertical velocity of the slider on the characteristics of gouge damage are studied. The results show that in the process of sliding electrical contact, the magnetic field and current would gather on the sliding electrical contact interface and thus lead to a concentrated temperature rise at the end of the slider. Additionally, the greater the velocity of the slider, the more obvious the VSE becomes. The results also show that the vertical velocity plays a vital role in the morphology of gouge crater. When the vertical velocity is relatively high, a new gouge crater may appear based on the original damage. The critical vertical velocity that would induce gouge damage is also discussed in this article.

This article proposes two complementary Yagi-Uda antenna configurations based on hybrid metal-graphene materials with the exploration of surface plasmon polariton (SPP) mechanism for enhanced performance at the THz regime. These antennas are compared with the estimated outcomes in terms of impedance matching, directivity, radiation pattern, and front-to-back ratio. The SPP mechanism plays a crucial role in optimizing the performance by influencing the dispersion properties and mode propagation. The antenna configurations provide −10-dB impedance bandwidths of 10.59% (2.87–3.19 THz) and 22.95% (2.7–3.4 THz). The maximum achieved gain and efficiency are 7.8 dBi and 84.43%, respectively. The performance of the antenna is validated using analytical optimization at the THz regime, incorporating plasma frequency and collision frequency effects. In addition, the equivalent circuit model is analyzed and explored using advanced system design (ADS) to compare the antenna performance with conventional approaches. Moreover, this work provides a significant analysis of modes pertaining to the radiating elements, which efficiently predict the far-field characteristics of the antenna. The existence of higher order modes TM24 and TM44 is analyzed. To address the existence of these modes, a machine learning (ML) technique based on a convolutional neural network (CNN) model is adopted for mode mapping, involving data cleaning, feature extraction, and normalization. Thus, the performance of the antenna is rigorously validated by employing both analytical and ML approaches, with the exploration of SPP mechanism in hybrid material-based nanoantennas at the THz regime.

The Blumlein rectangular pulse generator is suitable for the calibration of nanosecond impulse measurement due to its fast response and high-voltage gain. However, pulse waveform distortion commonly occurs, creating challenges for accurate measurement calibration. This article focuses on the coaxial Blumlein generator and systematically studies the factors influencing its output. Parasitic parameters around the load and switch are examined by circuit simulation in PSPICE. Taking into account the inherent properties of the coaxial cables, a simulation model is also developed in CST. The voltage drop in the pulse is analyzed in detail, focusing on the influence of propagation velocity. Additionally, the effect of the wound structure of the coaxial cable is simulated and verified through measurement.
