The anechoic coating capable of absorbing sound energy in low frequencies within broadband is essential to conceal underwater vehicles. However, the geometric deformation and modification mechanical parameters under hydrostatic pressure affect prediction absorption performance deep water environments. An embedded with tandem resonant voids proposed this work achieve quasi-perfect low-frequency absorption. analytical method based on effective medium approach numerical simulation are performed...
A three-stage W-band GaN monolithic microwave integrated circuit power amplifier (MMIC PA) is reported. Electron-beam lithography has been employed to define a 100-nm T-shaped gate on the AlGaN/GaN HEMT structure with ultrahigh aluminum content. The MMIC PA offers peak small signal gain of 16.7 dB in 90-97 GHz bandwidth. Moreover, it achieves 1.66-W (32.2 dBm) output at 93 continuous-wave mode, an associated added efficiency 21% and 13.7 dB. Most notably, density 3.46 W/mm 480-μm wide stage,...
Facing the demand of industry for metal surface detection, this article addresses segmentation defects. Metal defect has many technical problems, such as serious imbalance in quantity and distribution, low contrast, weak boundary information. To solve these proposes a multi-scale attention feature fusion module, normalized mean square frequency category weight strategy, biased training sampling category-boundary loss calculation strategy. The module fuses different levels information to...
Traditional optimization methods are not well suitable for thinning large arrays to obtain a low sidelobe level (SLL).The chaotic binary particle swarm (CBPSO) algorithm is presented as useful alternative the synthesis of thinned arrays.The proposed can be improved by nonlinear inertia weight with mutation increase diversity particles.Two examples have been and solved.Simulation results compare published verify effectiveness method both linear planar arrays.
In this paper, the cavitation and flow characteristics of unsteady liquid nitrogen (LN2) cavitating in a submersible pump are investigated through both experimental numerical approaches. The performance curve LN2 is obtained via measurement. Numerical simulations performed using modified shear stress transport k–ω turbulence model, incorporating corrections for rotation thermal effects as per Schnerr–Sauer model. framework verified by comparing morphology features with previously reported...
