Self-defense mainlobe interference and radar echo signals generated by real targets are same spatial angle, which seriously affect the performance, so self-defense suppression is one of hot spots difficulties in current field. In order to solve this issue, an approach self-dense proposed. Firstly, pulse suffered rejected. Then, based on modified iterative method with adaptive threshold, interfered reconstructed along slow time. Simulation results indicate that proposed not only could...
In this paper, split ring unit cells are proposed and designed for ultra-wideband RCS reduction. The cell converts the incidence wave to its cross-polarization in wide bandwidth, most importantly, cross-polarized reflection phase amplitude can be separately controlled by geometry rotation angle. Based on diffuse theory, of tailored form a ultrawide band reduction metasurface. metasurface demonstrate 10 dB range 8.75 GHz-24.7 GHz.
Despite of various advantages, transmitarray antennas usually suffer from the limited bandwidth. In this paper, ultra-wideband polarization conversion elements are employed to design linearly antennas. The proposed transmissive element is a multilayered structure with asymmetric split circular ring in middle layer and orthogonal metal gratings at outermost layer. features high efficiency transmission capability, phase coverage 360° good linearity. By employing elements, an polarized antenna...
The study aims to investigate the effect of ginsenoside Rb1 on improving neutrophil extracellular traps-induced vascular endothelial damage. CCK8 assay was used evaluate impact cell activity. Flow cytometry assess apoptosis. E-cadherin determine damage cells, and caspase 3 detect apoptosis-related proteins. Ginsenoside (100 μmol/L) could significantly increase viability (p<0.05). At this concentration, caused by traps human umbilical vein cells be reversed inhibit apoptosis expression...
In this paper, a dual frequencies and bidirectional functional metasurface is presented. The can achieve radiation with polarization at different frequencies. By independently adjusting the reflection transmission phases, forward backward beam convergence be achieved. simulated results indicate that gain of reach 24.9 dBi 9 GHz 26.1 12 GHz, which least 13.5 higher than bare feeder.
