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 ...
Scattering of E. M. waves from dielectric density fluctuations
(1984-01)
Radars are used for remota probing of the upper atmosphere. Monstatic and bistatic configurations have been used. The echoes are obtained from the scattering of the illuminating wave by fluctuations in the dielectric ...
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 ...
Properties of Atmospheric Pressure Ar Plasma Jet Depending on Treated Dielectric Material
(2017-02-01)
Atmospheric pressure plasma jet operated in argon was utilized to modify surfaces of glass, acrylic, and PTFE dielectrics. This paper describes the influence of the dielectric substrate on operation and properties of plasma. ...
Electron Emission from Electron-irradiated Dielectrics
(1991-01-01)
The paper discusses methods for the measurement of the electron emission currents and the secondary electron yield for electron-irradiated dielectrics. Here the surface of the irradiated dielectric acts as both a collector ...
Influence of Molecular Dynamics on the Dielectric Properties of Poly(9,9-di-n-octylfluorene-alt-benzothiadiazole) -Based Devices
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
This paper uses Nuclear Magnetic Resonance (NMR) and Differential Scanning Calorimetry (DSC) techniques to study the molecular relaxations and phase transitions in poly(9,9-di-n-octylfluorene-alt-benzothiadiazole) (F8BT), ...
Domain wall contribution to dielectric and piezoelectric responses in 0.65Pb(Mg1/3Nb2/3)-0.35PbTiO(3) ferroelectric ceramics
(Iop Publishing Ltd, 2009-06-07)
In this paper, the contribution of the domain walls motion to the dielectric and piezoelectric responses for the 0.65Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3) system is investigated. A monotonically increasing temperature dependence ...
