A novel design of metamaterial (MTM) based absorber with reduced cell size is proposed in this paper. The absorber is designed to operate in the mid infrared (IR) regime using gold nano-pillar inclusions embedded in a dielectric spacer. The absorption band can be controlled by adjusting the nano-pillar’s properties. Numerical simulations have been conducted to investigate the effect of these in...

Serious cases of corrosion of metallic structures under both alternating current (ac) and cathodic protection (cp) have been reported. The objective of this research is to propose a mechanism by which ac affects the nano sized/structured surface films formed on metals under cp. A model will be proposed and experimentally validated, in order to relate the metal corrosiveness to its nano sized/st...

Metal Matrix composites (MMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence and other industries. MMCs are projected to significantly reduce the overall weight of the vehicle and aircraft while maintaining satisfactory structural strength. Micron and Nano-sized ceramic particle reinforced aluminum matrix composites fabricat...

– We calculate the electrical conductivity of a thin crystalline strip of atoms confined within a quasi one dimensional channel of fixed width. The conductivity shows anomalous behavior as the strip is deformed under tensile loading. Beyond a critical strain, the solid fails by the nucleation of alternating bands of solid and smectic like phases accompanied by a jump in the conductivity. Since ...

The authors describe a method to produce gold nanoparticle-dispersed liquid crystals by means of sputtering, and discuss how the presence of gold nanoparticles affect the electro-optic response of the host liquid crystal. The method exploits the fact that liquid crystals possess low vapor pressures which allow them to undergo the sputtering process, and the target material is sputtered directly...
