Shape of Dielectric Absorption Curves in Solid Linear High Polymers

High Frequency Loss Mechanism in Polymers Filled with Dielectric Modifiers

We analyzed the high frequency dielectric relaxation mechanism in high-k composite materials using film substrates made of low loss organic resin filled with ferroelectric ceramics and with single wall carbon nanotubes (SWNT). We performed broadband permittivity measurements of high-k film substrates at frequencies of 100 Hz to about 10 GHz. In order to analyze the effect of the dielectric thic...

High frequency dielectric relaxation in polymers filled with ferroelectric ceramics

We investigated the dielectric relaxation process in high-dielectric constant polymer composite films filled with barium titanate particles. In order to extend the dielectric measurements to the microwave range, we employed a new broadband measurement technique where a thin film capacitance terminating a coaxial waveguide is treated as a transmission line. The complex permittivity, measured at ...

TENSION QUARTIC TRIGONOMETRIC BÉZIER CURVES PRESERVING INTERPOLATION CURVES SHAPE

In this paper simple quartic trigonometric polynomial blending functions, with a tensionparameter, are presented. These type of functions are useful for constructing trigonometricB´ezier curves and surfaces, they can be applied to construct continuous shape preservinginterpolation spline curves with shape parameters. To better visualize objects and graphics atension parameter is included. In th...

Modeling Dielectric Absorption in Capacitors

Version 2c, 3 October 2004 It is well known that dielectric absorption plays a critical role in determining the accuracy of analog sampled-data systems that are based on charge storage, such as sampleand-holds and switched-capacitor ADCs. Less appreciated, but no less important, is the role it plays in determining the quality factor, or Q, of the capacitor. Dielectric absorption has both storag...
