In millimeter-wave (mmW) and terahertz (THz) applications, the transmission behavior along circuit structures components, such as radiation leakage losses, is critical for their overall performances. It imperative to develop low-loss interconnect techniques that should be used construction of building blocks elements. this work, a hybrid metallo-dielectric (MD) waveguide architecture proposed studied first time. The scheme made mixed substrate-integrated dielectric (SIDW) nonradiative...
The current work investigated the impact of transverse static magnetic field (TSMF) with varied flux density (MFD) on cleanliness and microstructure laboratory scale electroslag remelted H13 die steel. inclusion morphology evolution ingots were examined utilizing scanning electron optical microscopes, respectively. number size inclusions in detected using FEI Aspex Explorer. results demonstrated that number/size decreased as MFD applied TSMF increased. This resulted from application TSMF,...

NRD with metallic covers used allows suppressing potential radiation leakage effects, whereas DW adopted along...
Purpose This study empirically examined four value attributes (e.g. conditional value, functional epistemic and price consciousness) influencing young customers’ attitudes, word-of-mouth (WOM) continuous usage intentions. Subjective norm was positioned as the moderator, while WOM identified mediator. Design/methodology/approach collected data from 252 Chinese customers using purposive sampling technique utilized PLS-SEM to examine interrelationships among variables. Findings The findings...

5G New Radio (NR) promises to support diverse services such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type (mMTC). This requires spectrum, most of which is occupied by 4G Long Term Evolution (LTE). Hence, network operators are expected deploy using the existing LTE infrastructure while migrating NR. In addition, must legacy devices during migration, so NR systems will coexist for foreseeable future. this article, we address...
