Microstrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials

Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...

A Transmission Electron-Microscopy Study of RF-Magnetron-Sputtered and DC-Magnetron-Sputtered Thin-Film Chromium and Chromium Platinum Coatings

Microstructural features of sputtered chromium and chromium-50 wt. % platinum thin films on carbon substrates are presented. Films produced by rf sputtering and dc magnetron sputtering are compared using analytical electron microscopy techniques. All rf-sputtered films are uniform in chemistry and thickness and are amorphous. The chromium film became crystalline with a grain size ofless than 10...

Liquid crystal clad near-infrared metamaterials with tunable negative-zero-positive refractive indices.

Near-infrared metamaterials that possess a reconfigurable index of refraction from negative through zero to positive values are presented. Reconfigurability is achieved by cladding thin layers of liquid crystal both as a superstrate and a substrate on an established negative-index metamaterial, and adjusting the permittivity of the liquid crystal. Numerical results show that the index of refrac...

Effect of DC power on the AlN plasma of magnetron sputtered thin film

AlN thin films deposited at room temperature by reactive DC magnetron sputtering of Al target in pure argon and nitrogen atmosphere. Thin films were deposited on glass and silicon (Si) substrate at different DC power. The variation of DC power on the structural, electrical and optical properties of the films were investigated. Enhancement of crystallinity and conductivity was observed with incr...

Transparent Thin-Film Transistors Based on Sputtered Electric Double Layer

Electric-double-layer (EDL) thin-film transistors (TFTs) have attracted much attention due to their low operation voltages. Recently, EDL TFTs gated with radio frequency (RF) magnetron sputtered SiO₂ have been developed which is compatible to large-area electronics fabrication. In this work, fully transparent Indium-Gallium-Zinc-Oxide-based EDL TFTs on glass substrates have been fabricated at r...
