Form and Capacitance of Parallel-Plate Capacitors

AbstructIn basic electrostatics, the formula for the capacitance of parallel-plate capacitors is derived, for the case that the spacing between the electrodes is very small compared to the length or width of the plates. However, when the separation is wide, the formula for very small separation does not provide accurate results. In our previously published papers, we use the boundary element me...

Capacitance of Biconical Antennas in Magneto - Ionic Media ; Elliptic Cone Capacitance

Two antenna capacitance problems a re solved in this paper. The motivating problem was to determine the capacitance of a biconical antenna of circular cross section immersed in a magneto-ionic medium. This is solved by reducing it to the secondary problem of determining the capacitance of a biconical antenna of elliptic cross section in an isotropic medium. The latter is solved using the sphero...

Accurate Model of Capacitance for MEMS Sensors using Corrugated Diaphragm with Residual Stress

In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...

Low Value Capacitance Measurement System with Adjustable Lead Capacitance Compensation

The present paper describes the development of a low cost, highly accurate low capacitance measurement system that can be used over a range of 0 – 400 pF with a resolution of 1 pF. The range of capacitance may be easily altered by a simple resistance or capacitance variation of the measurement circuit. This capacitance measurement system uses quad two-input NAND Schmitt trigger circuit CD4093B ...
