Despite the simplicity of the hexagonal graphene structure formed by carbon atoms, the electronic behavior shows fascinating properties, giving high expectation for the possible applications of graphene in the field. The Graphene Nano-Ribbon Field Effect Transistor (GNRFET) is an emerging technology that received much attention in recent years. In this paper, we investigate the device performan...

Dielectric heating is one of the most promising alternatives to conventional thermal treatment fluid foods. Higher efficiency and better uniformity radio frequency microwave processes have been proven successful in providing a similar or bacterial enzymatic inactivation liquid semi-solid foods while improving sensory nutritional qualities fresh product when compared pasteurization. However, fur...

Experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-BD, in2-ethyl-1-hexanol, 2EH, were reported for various mole fractions and temperatures (298.2-308.2) Kand they were used to calculate dielectric parameters such as Kirkwood correlation factor, excesspermittivity and Bruggeman parameter. These parameters were used to carry out temperaturedependent die...

Traveling Wave Tubes (TWTs) consist of different elements. The most important element of TWT is the RF circuit. RF circuits in helix TWTs need a dielectric support to hold the helix; this support also has an effect in electromagnetic properties of RF circuits. A novel dielectric support is proposed to reduce the second harmonic of helix TWTs. The dielectric support in this structure consists of...

The Fano resonance demonstrates excellent performance due to its narrow asymmetrical spectral line shape, and sensitivity structure material parameter changes. Compared conventional resonances, the generated by magnetic dipole is more advantageous because of high absorption low loss. In this study, we propose an Au nanosphere dimer–dielectric–gold film sandwiched that supports mode. And can be ...

Reduction in surface and interface reflectance via the integration of subwavelength nanostructures in flexible polymer packaging material combined with incorporation of dielectric nanoislands into a conventional two-layer antireflection coating has been demonstrated, analyzed and optimized. Transmittance measurements of moth-eye textured polymer packaging sheets with different tapered pillar he...

Novel ferromagnetic-dielectric particulate composites of Ni0.5Zn0.5Fe1.95O4−δ (NZF) and PbZr0.52Ti0.48O3 (PZT) were prepared by conventional ceramic method. The presence of two phases in composites was confirmed by XRD technique. The variations of dielectric constant (ε) with frequency in the range of 100 kHz–1MHz at room temperature and also with temperature at three different frequencies (50 ...

A one-dimensional photonic crystal (PhC) with termination by a metal film—a plasmonic photonic-crystal slab—has been theoretically analyzed for its optical response at a variation of the dielectric permittivity of an analyte and at a condition simulating the molecular binding event. Visualization of the Bloch surface wave resonance (SWR) was done with the aid of plasmon absorption in a dielectr...

In the past decade, dielectric elastomers have emerged as promising multifunctional smart energy-transduction materials in several actuation, sensing, and electric power generation applications. As actuators, dielectric elastomers have demonstrated strains (over 300%) and specific energy density (over 3.4 J/g) larger than that observed in any other field-activated smart material. In generator m...
