Abstract In this paper, a polarization-reconfigurable antenna fed by coplanar waveguide (CPW) using stepped structure is presented. The main parts of the proposed consist CPW-fed monopole and four branches. After studying analyzing mechanism antenna, it was found that different polarizations can be generated adjusting antenna’s structure. Based on mechanism, PIN diodes are utilized inserted between branches for switching. By controlling ON/OFF states diodes, switch among left-hand circular...

The different polarizations combined optimized, so as reduce mutual influence between them. way, realized. rectifier half-wave rectifying structure adopted converting...
This Letter presents a crystalline silicon thin film solar cell model with Si nanowire arrays surface decoration and metallic nanostructure patterns on the back reflector. The nanostructured Ag reflector can significantly enhance absorption in near-infrared spectrum. Furthermore, by inserting ZnO:Al layer between substrate reflector, loss be clearly depressed, contributing to maximum J(sc) of 28.4 mA/cm(2). A photocurrent enhancement 22% is achieved compared SiNW planar
A crystalline Si thin film solar cell with elliptical silicon nanowire (SiNW)-decorated surface is presented. The SiNW performs broadband light absorption in the low energy region while maintaining strong high region. For cells 1-μm underlying substrate, J sc can be improved to 24.2 mA/cm 2 , which 16% higher than that of circular SiNW-decorated cells. After integration an Ag reflector, achieve 26.3 demonstrating a photocurrent enhancement 12.6% as compared control device.
This article mainly focused on the seismic performance of steel reinforced recycled concrete frame structure under low-cyclic reversed loading. To evaluate structure, a two-span three-storied was conducted at civil engineering laboratory Xi’an University Architecture and Technology. Experimental numerical studies were implemented to investigate crack status, failure modes, hysteresis loops, skeleton curves, energy dissipation capacity, load–displacement P-Δ effect, influence strength Results...
The fruits of Solanum torvum Swartz, a wild relative eggplant, are consumed as vegetable in tropical regions Africa, Asia, and South America. In traditional Chinese medicine, it is believed to have anti-inflammatory sedative effects. the Philippines, water decoction used treat hyperactivity disorder. Twenty-two steroidal saponins were isolated purified from grown Yunnan, China, including six new compounds: torvosides U–Z (1–6). During drying cooking, may undergo transformation, resulting...
