Techniques for capacitor dielectrics characterization

2020
Electrostatic capacitors are indispensable components in high voltage pulsed power systems and power electronics. They are widely employed in applications such as pulse-forming networks, switched-mode power supplies, medical defibrillators, and power electronics in hybrid electric vehicles (HEY), grid-tied wind turbine generators, high-speed trains ...

Broadband microwave dielectric characterization method for printable dielectric inks

2017 89th ARFTG Microwave Measurement Conference (ARFTG), 2017
This work presents a parameter-related, one-probe based microwave characterization method for determining complex dielectric properties of various printable dielectric inks from 1–30 GHz. Dielectric constant and loss tangent of a material under test (MUT) are extracted utilizing the measured reflection 511-parameters and analyzed equivalent circuits of

Parametric characterization of dielectric dispersion

Applied Physics A Solids and Surfaces, 1993
Dielectric dispersion is specified by introducing two novel distribution parameters. They are related to the charging and loss components of the complex dielectric constant. The parameters allow to present a complete description of dispersion, using multiple-arc analysis.

Characterization and Modeling of Dielectric Properties of Turkey Meat

Journal of Food Science, 2003
ABSTRACT: The dielectric properties of turkey meat at water activities of 0.84 to 0.98 were measured at 2450 and 915MHz. Equations were developed as a function of temperature, moisture, water activity, and ash, and compared to literature equations.

Dielectric Thermoscopy Characterization of Water Contaminated Grease

Tribology Transactions, 2017
The temperature dependence on the dielectric properties of water-contaminated grease is investigated in this article. The purpose of this investigation was to identify the dielectric properties that could be measured to differentiate varying levels of water contamination in calcium sulfonate complex (CaS-X) grease with three different test cells with ...

Thermal characterization of the VBIC dielectrically isolated device

2009 IEEE International Conference on Electro/Information Technology, 2009
This paper presents thermal characterization of the dielectrically isolated bipolar junction transistor (DIBJT) with the vertical bipolar inter-company (VBIC) model. The VBIC model incorporates the thermal nodes of a transistor. Semiconductor devices are strongly influenced by the thermal effects.

Note: Characterization of electrode materials for dielectric spectroscopy

Review of Scientific Instruments, 2010
When measuring the dielectric properties of aqueous samples, the impedance of the electrode/sample interface can limit low frequency measurements. The electrode polarization problem can be reduced by increasing the effective surface area of the electrodes.

Dynamics and Structure of Biopolyelectrolytes Characterized by Dielectric Spectroscopy

Macromolecular Symposia, 2011
AbstractStructural properties of Na‐DNA and Na‐HA aqueous solutions can be quantified using dielectric spectroscopy in the frequency range 100 Hz–100 MHz. Two relaxation modes are typically detected that can be attributed to diffusive motion of polyion counterions.

Compositional Characterization Of Dielectric Oxides

1986
Many oxides containing transition metal elements are used in electronic and optical applications that require that they be insulating or transparent. The chemical criteria for such behavior are reviewed, and the strong effect of even very small changes in composition are emphasized. In some cases compositional changes in the ppm range can cause changes
