We have examined the anisotropic terahertz response of highly aligned single-wall, double-wall, and multiwall carbon nanotubes and quantitatively characterized their performance as low-cost terahertz polarizers.
The plasmon characteristics in stage-1 graphene intercalation compounds (GIC’s) using the massless Dirac fermion (MDF) gas approximation have been reported. The superlattice model of GIC’s with negligible c-axis conductivity has been considered. With the discussion of the weak and the strong c-axis coupling at graphen…
Fiber-reinforced aluminum alloy composites were fabricated by squeeze casting, and the effects of the fiber reinforcement on the machinability of the alloy were investigated. Al-Si-Cu-Ni-Mg alloy was used as the matrix metal, and two kinds of short alumina fibers were used as the reinforcements. The cutting force valu…
Liquid crystal twisted-nematic polarization rotators in the Mauguin condition are shown to be more achromatic, less prone to high-frequency modulations caused by internal reflections than compound wave plates, and can be fabricated cost effectively at multi-inch apertures.
Phase and group propagation in metamaterial-based microwave components has always been intellectually challenging for students and engineers new to the area of periodic structures and metamaterials. This paper aims in tackling this important topic by studying the wave propagation in a metamaterial-based microwave devi…
Two kinds of novel blue-emitting materials, anthracene-based derivatives, are synthesized by the Suzuki coupling reaction. It is worth noting that the maximum emission wavelengths of the two materials are 441 and 444 nm in tetrahydrofuran and 456 and 454 nm in film states, which are the typical blue fluorescence and t…
Triple thin metal-film subwavelength gratings on both sides of a silicon substrate are fabricated for polarizers in the mid-infrared wavelength region of 10-20 |am. Measured TE-wave losses are higher than 30dB for the wavelength range, while the TM-wave losses are lower than 2.0dB in the wavelength range of 16.5–19.5μ…
In order to study the thermoelectric properties of TiO2-based hybrid materials, TiO2/polyparaphenylene(PPP)nanocomposites are fabricated by spark plasma sintering(SPS). The results show that the electrical conductivity follow percolation theory is enhanced due to the electron transfer highway provided by the conductin…
Experimental measurements of the products of fission reactions are generally biased by evaporation stages before and after the fission process. Its complexity needs as many observables as possible to check the present models and reveal new correlations. Fully identified fission fragments and their velocities can provi…
We propose a post-processing approach for tuning terahertz metamaterials by modifying the coupling between two metamaterial layers. We demonstrate that this method allows the metamaterial resonance to be shifted by 31% of the central frequency.
Conducting polymers have become the focus of research due to their interesting properties, such as a wide range of conductivity, facile production, mechanical stability, light weight and low cost and the ease with which conducting polymers can be nanostructured to meet the specific application. They have become valuab…
Diamond films exhibit interesting properties, such as a wide bandgap (5.5 eV) and very low electron affinity which favours the electron photoemission. Diamond based cold photocathode is well known and demonstrated, due also to its chemical stability and mechanical robustness. In this work, a comparative study on photo…

First principles study of structural and electronic properties of non- magnetic LaSn 3 and CeSn 3 as well as ferromagnetic PrSn 3 and NdSn 3 rare-earth intermetallic compounds, which crystallize in AuCu 3 -type structure, is performed using density functional theory based on full potential linearized augmented plane w…
Amorphous HfO2nano-helix arrays with different screw pitches were fabricated by the glancing angle deposition technique. Room temperature ferromagnetism was achieved in this undoped amorphous HfO2 nanostructure, which is attributed to singly charged oxygen vacancies. The different magnetic behavior and photoluminescen…
We present a widely tunable polarization converter with ultra-broad working frequency for microfluidic metasurface. By adjusting the configuration of L-shaped antenna, both cross and circular polarization conversion can be achieved under a linear-polarized illumination.
In this paper, we summarize the research development of low-frequency oscillations in the last few decades. The findings of physical mechanism, characteristics and stabilizing methods of low-frequency oscillations are discussed. It shows that it is unreasonable and incomplete to model an ionization region separately t…
Complex-linearization of a class of systems of second order ordinary differential equations (ODEs) has already been studied with complex symmetry analysis. Linearization of this class has been achieved earlier by complex method, however, linearization criteria and the most general linearizable form of such systems hav…
Based on reported experimental data, a new model for single cavitation bubble dynamics is proposed considering a supercritical water(SCW) shell surrounding the bubble. Theoretical investigations show that the SCW shell apparently slows down the oscillation of the bubble and cools the gas temperature inside the collaps…
