Sensor para análise das características físico-químicas de óleo de soja por meio da constante dielétrica
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2015-03-27)
This paper proposes the use of a capacitive sensor for determining the dielectric constant to characterize vegetable oil samples before and after the frying process. In tests, the fry was simulated by heating oil subjected ...
Potassium niobate thin films prepared through polymeric precursor method
(Elsevier B.V., 2004-08-01)
Thin films of potassium niobate were deposited on (100) Si substrates by the polymeric precursor method (Pechini method). Annealing in static air was performed at 600degrees C for 20 h. The obtained films were characterized ...

Determination of plasma frequency, damping constant, and size distribution from the complex dielectric function of noble metal nanoparticles
(American Institute Of Physics, 2014-11)
This paper develops a novel method for simultaneously determining the plasma frequency ωP ωP and the damping constant γfreeγfree in the bulk damped oscillator Drude model, based on experimentally measured real and ...
Structural and dielectric properties of relaxor Sr0.5Ba 0.5Bi2Nb2O9 ceramic
(2010-03-01)
Sr0.5Ba0.5Bi2Nb2O 9 ceramic was prepared by a conventional solid state reaction method and studied using X-ray powder diffraction and dielectric measurements. At room temperature, an orthorhombic structure was confirmed ...

Influence of micro and nanoparticles of zirconium oxides on the dielectric properties of CaCu3Ti4O12
(Elsevier, 2017)
This work presents the results of Zr oxide doping of a CaCu3Ti4O12 (CCTO) ceramic prepared by a solid-state reaction. Different stoichiometries (ZrO and ZrO2) and grain sizes (micro- and nanoparticles) were added as dopants ...
Fast analysis of cylindrical microstrip lines printed on substrates composed of multiple layers
(John Wiley and Sons Inc., 2010)
This letter presents an analysis of microstrip lines that are printed on substrates composed of numerous dielectric layers using a fast technique that comprises the full-wave equivalent circuit and the discrete mode matching ...
Static dielectric constants of acetonitrile/water mixtures at different temperatures and debye-hückel A and a0B parameters for activity coefficients
(American Chemical Society, 2007-05)
Static dielectric constants of acetonitrile/water mixtures in the whole composition range and within the temperature range from (15 to 60) °C have been measured. The values were fitted to a unique equation as a simultaneous ...
