It is defined as capacitance per unit mass, per unit area, or, per unit volume, and corresponding specific capacitance is known as gravimetric capacitance (F/g) or areal capacitance (F/cm2) or volumetric capacitance (F/cm3) respectively. Now capacitance is given by charge divided by volt C...
The capacitance of an arbitrarily shaped object is calculated with the same second-kind integral equation method used for computing static and dynamic polarizabilities. The capacitance is simply the dielectric permittivity multiplied by the area of the object and divided by the squared norm of the Neu...
separated by a thin, nonconducting sheet such as paper, and then the whole assembly can be rolled up to get a large effective surface area. When this is done, the electric flux becomes great enough so that the device exhibits significant capacitance. ...

The design is divided into areas. Capacitance effects for each area are estimated based on the congestion ratios within the area. The congestion ratios for each area are derived from estimations of the demand for routing resources in each area for each net in the net-list included in the IC...
1. The effective area of the plates. Capacitance, which is directly proportional to the effective area, is increased by increasing the number of plates (e.g., stacked plates) or the total area of the plates (e.g., rolled capacitors). ...

The capacitance of a parallel plate capacitor is given byC=εrA/d. The energy stored in a capacitor is calculated by the work done in moving charge onto the plates.dW = V dq. The energy store is the area under the charge/voltage plot. 1/2QV or from C=Q/V, 1/2CV2= 2Q2/C....
A capacitor can be made variable rather than fixed in value by varying any of the physical factors determining capacitance. One relatively easy factor to vary in capacitor construction is that of plate area, or more properly, the amount of plate overlap. ...
