CoY hexaferrite-filled PEEK (poly ethyl ether ketone) compositeswere synthesized to characterize the effect of hexaferrites on their dielectric, magnetic and thermal properties for wireless sensing and communication applications. Fillers were synthesized from solid-state reaction route and blendedwith the thermoplastic polymermatrix.XRDwas used to study the phase purity of the synthesised fille...

Abstract We showed that the ferromagnetic correlation extended far into what was thought to be paramagnetic phase for pristine Ca 3 Co 2 O 6 in our Bi-substituted compound and found a between magnetic dielectric anomaly this region. have observed enhancement of property (dielectric constant 200 with loss factor 0.01 at 1 MHz), which is attributed high ionic polarizability Bi. The response curve...

In this research, BaTiO3 thick deposit has been successfully sprayed by air plasma spray. The microstructure and dielectric properties of thick films were investigated by secondary electron microscopy (SEM) and LCR meter respectively. XRD measurement was carried out on plasma sprayed BaTiO3. The results illustrate differences in the crystal structure between plasma sprayed coatings and feed sto...

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...

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 effective planar elastic moduli and planar conductivity (or dielectric constant) of regular hexagonal and triangular honeycombs were investigated for the entire range of volume fractions. Only the extreme limits of the volume fraction have been studied in the past. We studied the effective properties both numerically, via finite elements, and analytically, via rigorous three-point bounds, t...
