An electrical capacitance tomography

6th International Conference on Signal Processing, 2002., 2003
This paper reports on a study determining the capacitance from given permittivity patterns and describes the image reconstruction method for electrical capacitance tomography (ECT). The model described in this paper is a square object with 8 electrodes. The finite difference method and Gauss's law are used for calculating numerically the capacitance of

Calculation of the Electrical Capacitance of a Cube

Journal of Applied Physics, 1951
The basic theory of calculation of the capacitance of a given geometrical configuration by the use of subareas is advanced and applied to solve the long-standing problem of the accurate evaluation of the capacitance C of a cube of side a. The best previously published determination is 0.62211a<C<0.71055a.

Optimized design and simulation of electrical capacitance sensor for electrical capacitance tomography system

SPIE Proceedings, 2002
In this paper a software method for electrical capacitance sensor design of electrical capacitance tomography system is presented by using finite element analysis techniques. Electrical capacitance sensor theory model is established, and capacitance sensitivity field distribution and structure parameters of the sensor to measurement effect are analyzed

The Electrical Capacitance of Small Systems

Journal of Colloid and Interface Science, 2000
The electrical capacitance of several small systems is determined by using results given by the fluctuation-dissipation theorem in the classical limit. Estimating the electrical capacitance is important because it is the link to knowledge of the fluctuation of several physical quantities, voltage and field fluctuations, dipole moment, pH, and charge ...

Electrical Capacitance Tomography with a variable topology

2015 9th International Conference on Sensing Technology (ICST), 2015
In this paper we present a novel approach for Electrical Capacitance Tomography (ECT) with a variable electrode topology of the sensor front end. The topology of the ECT can be continuously varied while the reconstruction takes place. The unique combination of light weight signal processing chain with a variable dual plate planar sensor front end meets
