This letter presents a novel broadband microstrip patch antenna with simple geometry. Two parasitic mushroom-type arrays are incorporated along the two radiating edges of main patch. First, thanks to structure, new resonant mode, characterized as quasi-TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">30</sub> is generated. Besides, produces original TM xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> mode. Thus, wideband performance...
In this paper, a planar reflectarray antenna employing equivalent magnetic dipole (EMD) elements is proposed. An H-shaped patch and two coupling T-shaped patches are employed as the EMD element, in which electric current intrinsically flows on central while with orthogonal direction can be ingeniously excited meanwhile due to adjacent gaps. Compared conventional magnetoelectric dipoles, single-layer element eliminates vertically metallized via structure generates an help of displacement...

Accordingly, unit cells designed arranged an array with equivalent gradient refractive index diameters achieve good wave focusing...
With the development of space missions, increasing communication data volume, diversity mission-specific interfaces, and growing security needs, costs system complexity ground stations have increased. The architecture existing terminal is outdated operation maintenance are labor-intensive, so components unable to meet demand multi-satellite TT&C in future. In this paper, a Shared Satellite Ground Station(SSGS) using user-oriented virtualization technology proposed for coping with complex...
Pentamode material (PM) possesses great potential in underwater acoustic metamaterial device applications due to its broadband and solid-state merits. Previously proposed PM devices are all designed with single materials, where the additional weights for mass adjustment connected directly struts modulus adjustment. The coupling effects between them severely restrict available fabrication techniques realizable range of physical properties devices. A multiphase configuration, which bonded...
Intercellular signal transduction plays an important role in the regulation of biological activities. Herein, a Transwell chamber-based two-layer device combined with scanning electrochemical microscopy (SECM) technology has been proposed for situ investigation intercellular transduction. The cells were cultured on two layers: lower layer was signaling cells, and upper signal-receiving cells. extracellular pH (pHe) ROS (reactive oxygen species, ROSe) monitored by SECM potentiometric mode...
A programmable multitarget-response electrochemical imaging technique was presented using scanning microscopy (SECM) combined with a self-designed waveform. The potential waveform applied to the tip decreased charging current caused by switch, enhancing signal-to-noise ratio. This SECM (P-SECM) method used scan metal strip for verifying its feasibility in feedback mode. Since it could achieve simultaneous multitarget during one single process, PC12 cells status imaged and identified through...

The operates at Ku band, which above the operating X band. advantages this configuration are that smaller size has less shielding reradiation energy, property bottom substrate no effect on up‐layer due to severs as ground plane. Furthermore, two orthogonal polarizations produced by radiation characteristics metal strip eliminate coupling. Based...

In space information networks, satellites are generally in high speed orbit motion. order to obtain better spacial and temporal coverage performance, should cooperate with each other as a constellation. Previous works on constellations mainly focus global seamless using fewer satellites. However, like most countries, it is hard for China build ground stations overseas, the geostationary Earth position resource scarce. this paper, we investigate constellation design problem restricted...
In spacecraft networks, the time-varying topology, intermittent connectivity, and unreliable links make management of network challenging.
