What is the electric field distribution of a point-to-ring electrode configuration?

05 May 2018 0 3K Report

Dear researchers,

The electric field distribution of some common electrode configurations can be generally summarised with equations. For instance, the E-field distribution of a point-to-plate configuration is as follow: E = 2V/((r+2x)*ln(2d/r+1)) [From: A. Fridman and L. A. Kennedy, Plasma Physics and Engineering, 2nd Edition, CRC press]

However, I am having difficulty on finding such distribution for a point-to-ring electrode configuration. May I ask if anyone have such information?

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
